Plants vs. Zombies: Island Quest (abbreviated as PvZ:IQ, Island Quest, or just IQ) is a tower defense game released by Sani StudiosTM. This game puts you in the middle of a mysteriously eerie Archipelago, a land filled with wonder and awe - and zombies, apparently! In Island Quest, you must go out into the Archipelago and save it from the evil zombies that want to attack it - this is effectively the base of any Plants vs. Zombies game, so you should really know this by now. However, what you might not know is that this game also allows you to play as those evil zombies and crush the plant resistance. It's great! Out there is an entire world of mystery and wonder to discover, filled with awesome plants, disputably cool zombies, and exotic chickens. Ok, that last one's a lie. The chickens didn't show up on time.
== Plot ==
Plants vs. Zombies: Island Quest takes place in the serene yet restless Archipelago, where the battle between plants and zombies continues to run rampant. Dr. Zomboss has come up with yet another diabolical scheme with the help of his all-new and all-evil Tropi-Tech™ developments to take over the Archipelago and all of its constituent islands, sapping their inherent magical energy to power his toaster. At the heart of the Archipelago lies the all-powerful Heart of the Sea, the key to Dr. Zomboss's toaster-powering plan! Plants and zombies alike race to locate the mysteriously powerful artifact as they explore strange and mysterious new worlds...

==Game Mechanics==
<tabber>
|-|Plant Side=
Sun is the main currency used in the actual battles in the Plants vs. Zombies series. As in every Plants vs. Zombies game, it is used to plant your plants so that you can defend against the zombies! Each sun collected is worth 1, the same sort of scaling featured in Plants vs. Zombies 3. Sun falls from the sky in all levels, since the entire game takes place during the day due to the lack of mushrooms, every 9-10 seconds or so. Levels start off with some sun as well to get you on your feet, although some later levels don't start with much at all.
Shovel is an item that is used to dig up plants. The shovel does not cost the player any sun to be used, meaning it can be used an infinite amount of times in a single level as long as the player has plants to remove on the lawn. The player cannot get any shoveled up plants back in any way (of course, other than replanting them). The shovel has no cooldown or other restrictions on how often it can be used, meaning that no matter how many mistakes you make you will always be able to fix them. As an added benefit, you get 33% (rounded down) of the sun used in planting the plant back when it's shoveled up. Handy!
Seed Packets dictate how many plants you are allowed to bring into a level. You only get 5 seed packets in this game, which is significantly fewer than some other games, but there's some thought behind that decision. Since the roster of plants is so small, you don't really need to be running around with as many different plants especially because there are not as many choices. There are also not as many different support plants to pick, so that's why there's not as much space. Players can choose to randomize all or some of their seed packets and will find out what was chosen when the level starts.
Coins are the main currency used in Island Quest to purchase shiny and exciting things from the Shop. Coins are earned by completing levels, based on the number of zombies you fought in that level. When the level ends, a number of gravestones will pop up from the ground all over the lawn and burst into coins based on how many zombies were defeated (ignoring spawned ones), and based on the general strength of the zombies fought as well. The exact values are listed below in the Zombipedia, but just know that it does scale based on overall difficulty. You also earn coins by completing minigames through the Party Yacht, because OF COURSE!
|-|Zombie Side=
Moon is the main currency used in the actual battles in the Plants vs. Zombies series. In Island Quest, moon is used to deploy zombies to attack the plants like I, Zombie from the first game. Each moon collected is worth 1, the same sort of scaling featured in Plants vs. Zombies 3. Moon is obtained when zombies eat sun-producing plants like Sunflower, Twin Sunflower, and any others. Levels start off with some moon as well to get you on your feet, although some later levels don't start with much at all.
Zombie Packets dictate how many zombies you are allowed to bring into a level. You only get 6 zombie packets in this game, which is significantly fewer than some other games, but there's some thought behind that decision. When compared to the plant side, you get an additional slot because you generally need to be running more different zombies for different situations than you would in plant levels. Players can choose to randomize all or some of their zombie packets and will find out what was chosen when the level starts.
Coins are the main currency used in Island Quest to purchase shiny and exciting things from the Shop. Coins are earned by completing levels, based on the number of plants you fought in that level. When the level ends, a number of magical glowing roots will pop up from the ground all over the lawn and burst into coins based on how many plants were defeated (ignoring spawned ones), and based on the general strength of the plants fought as well. The exact values are listed below in the Tropicalmanac, but just know that it does scale based on overall difficulty. You also earn coins by completing minigames through the Party Yacht and by completing Shipwreck, because OF COURSE!
</tabber>
==Great Library==
The Great Library is an ancient place that houses just four books (money's kinda tight in this economy), each possessing an unreasonable amount of knowledge that no player would ever dream of having. Those books are the Tropicalmanac, the Super Tropicalmanac, the Zombipedia, and the Hero Zombipedia (plant almanac, super plant almanac, zombie almanac, and hero almanac for those with slower minds), which fill themselves out magically as you run into new characters, and give you all the nitty-gritty details: exact stats, names, artwork, and even descriptions. You'll find out about Super Plants and Heroes later on down the page. This is truly an amazing and wonderful feature. For zombies, their coin values are also shown. This is not the number of coins you can purchase the zombies with, but rather how many coins they turn into at the end of the level.

==Quest Boat==
Island Quest, like all Plants vs. Zombies tower defense games, consists of a bunch of normal levels. These Quest Boat levels allow you to unlock new plants and zombies, and experience new types of levels that you might not have otherwise been able to experience. The main Quest Boat adventure consists of 50 high-quality levels that span 5 different areas - there's only 10 levels per area, but each area feels fresh and a bit different than the last one. This game has no lives or energy systems, so you could complete the entire game in a day if you wanted to. You'd be missing out a bit in terms of the Shop, Zen Garden, Graveyard, and Party Yacht, but you could.
The main Island Quest campaign is split into Plant and Zombie Sides. The Plant Side levels are your typical plant-based levels with the normal mechanics you'd expect to find in a game like this, while the Zombie Side levels function like I, Zombie from the first game. Zombies can only be placed to the right of the 5th column normally, but it depends a bit on the level. You get to pick your plants for the Plant Side and pick your zombies for the Zombie Side, so you have full control over your destiny. Plant levels have multiple flags, while zombie levels have multiple consecutive stages instead.
===Emerald Isles===
The Emerald Isles is the name of the island where those 50 high-quality levels take place. The Emerald Isles are split up into There are a number of gimmicks present in its levels to spice things up and keep you on your toes, and while it's the same set for both the Plant Side and Zombie Side they have different effects on your gameplay depending on which side you're on. These are the gimmicks in the levels and their Plant/Zombie Side effects:
====Environment====
*Water! Water comes in two forms: Still and Flowing.
**Plant Side: Plants can't be planted on water without a Lily Pad. Zombie Side: No effect.
**Zombies move 25% slower when walking through Still Water. They move 50% slower when moving through Flowing Water that is flowing to the right and 25% faster when moving through Flowing Water that is flowing to the left.
*Dirt! Dirt's pretty filthy, if you catch my drift.
**Plant Side: Plants can't be planted on dirt, period. Zombie Side: No effect.
*Stone! Stone tiles are a rock-solid gimmick.
**Plant Side: Plants can't be planted on stone without a Flower Pot. Zombie Side: Zombies can't be placed on stone, period.
====Grid Items====
*Tropi-Tech™️! Dr. Zomboss's latest invention packs a punch!
**Plant Side: A grid item which blocks plant attacks and placement. Destroyed after taking 36 damage. Zombie Side: Gives your zombies cover, but blocks zombie placement.
*Roots! What's up with all of these glowing roots?
**Plant Side: Gives your plants cover, but blocks plant placement. Zombie Side: A grid item which blocks zombie attacks and placement. Destroyed after taking 75 damage.
===Shipwrecks===
Shipwrecks are randomly generated levels that can give you some coins if you're stuck on one of the Quest Boat levels. Three Shipwrecks are generated at a time per island and they vary in difficulty - Easy, Medium, and Hard with coin rewards depending on the difficulty. If you're not happy with one of the Shipwrecks, you can swap it out for a new one. In addition, when a Shipwreck is successfully completed it is immediately swapped out for a new Shipwreck. How does that actually work or make any sense? We'll just chalk it up to magic.
You can use Shipwrecks to collect coins if you're absolutely stuck on a level and purchase a Boost to get out of it. Of course, the game is completely doable without Boosts but this title is meant to be especially casual-friendly so it's just an option that exists. You'll also need to play Shipwreck levels after you complete the main Quest Campaign to earn coins for all the Shop things. As with everything else in this game, the Shipwrecks work for both plants and zombies. If you're on the Plant Side, the levels will work with normal plant gameplay. If you're on the Zombie Side, the levels will work with normal zombie gameplay.
==Party Yacht==
Party Yacht allows you to play some one-off minigames, as well as a handful of full "sets" of minigame content as well. There are, obviously, different minigames for plants and for zombies. These minigames can be completed to earn some bonus coins as well as for fun. That's also an important part of the game. We could give out hundreds of thousands of coins and it wouldn't mean anything if the minigames weren't fun. Each minigame also comes with a Hard variant that's meant to be a lot more challenging but allows you to collect the coin reward a second time. Party Yacht is unlocked after completing Level 30 in the Quest Boat campaign.
===Plant Side===
====Single Levels====
Remember that all Single Level levels have a Hard mode unlocked after they're completed. The goal of these levels is to be more difficult than the original level, not to be completely impossible.
*Slot Machine: Spin the slot machine with 1 sun to determine your fate. Collect a total of 100 sun to win!
*Invisi-ghoul: Zombies are invisible to the player but not to your plants. The win condition is that of a regular level.
*Portal Combat: Two sets of portals appear on the lawn, and everything that goes in one comes out the other. The win condition is that of a regular level.
*Column Like You See 'Em: When a plant is planted, the entire column is filled with that plant for valid spaces. Zombies will also appear on all five lanes. The win condition is that of a regular level.
*Zombie Trap: The goal is to lure zombies to a red rectangle, then signal ravens to drop cages on them, increasing brain count and cage availability with successful captures of 5 or more from an initial three brains and seven cages. The win condition is to trap and destroy a total of 50 zombies.
*Heavy Weapon: Players control a lawnmower armed with a Peashooter to fend off zombies, gradually upgrading it to shoot more peas and cover more lanes. It can collect sun that falls from the sky and is sometimes dropped by zombies to fund the upgrades. The win condition is that of a regular level.
*Zombie Nimble Zombie Quick: The game runs at three times the speed as other "normal" levels. This includes the speed and rate/pace of both zombies, plants, falling sun, and seed packets recharges. The win condition is that of a regular level.
*Seeing Double: Players have to manage two lawns at once, both under attack by zombies, by swapping between the two and planting their defenses. The win condition is that of a regular level.
*Corvus Catastrophe: Crows descend from the sky and try to take away your plants, but you can trick them into taking away zombies instead. There's a much higher concentration of zombies than usual, so you'll need to engage with this in order to win. The win condition is that of a regular level.
*Choy Chop: Zombies of different speeds run by, and you have to punch them using manually-activated pre-planted Bonk Choys in tune to the music to defeat them. Reach a certain core to win!
*Seed Packet Shuffle: Play with a random set of plants, which rotates out into another random set every 45s. The win condition is that of a regular level.
*Plant Sandbox: Complete all other Single Level and Level Set minigames to unlock the Sandbox. In the Sandbox, players can create their own custom levels or just play around with the game features. Up to 50 levels can be saved and shared via a link with other players.

Each Imp costs 5 moon, and players have 20 seconds to feed them before they expire.
*King of the Hill: Players deploy shields and zombies to defend against plants that approach from the left and launch projectiles at your base, and your cursor also acts as a shield. Blocking enough shots earns power-ups. The win condition is that of a regular level.

*Where To, Pal?: Players control a Zombie, maneuvering it with arrow keys between lanes across three different lawns, aiming to reach the opposite side while preserving five lives. The win condition is to successfully maneuver through all of the lawns without the Zombie being destroyed.
*It's Braining Seeds: Players collect seed packets of zombies which gradually fall from the sky, and are the only source of zombies. If the player does not plant a seed packet within 10 seconds of it landing, it will disappear. Every type of zombie can rain onto the lawn. The win condition is that of a regular level.
*Rampant Inflation: When a zombie is deployed, that type of zombie costs twice as much to use again for the rest of the level. The goal is to complete three stages without running out of moon, and the stages have more Sunflowers than they usually would.
*Taking Root: Both the player and the plant side start with no resources, with sun falling slightly faster for both sides, as you simultaneously build your zombie army and attack the plants with AI constructing their defense, aiming to win before two massive waves arrive.
*Nut Busters: Wall-nuts emerge from the ground for the player to tap and destroy in a similar fashion to Whack-a-Zombie. In occasion, Explode-o-nuts appear instead and accidentally tapping an Explode-o-nut costs one of three lives. Every type of zombie can rain onto the lawn.

==Battle Ship==
Battle Ship is a familiar PvP mode unlocked after completing level 50 in the Quest Boat campaign. The gameplay is much like any other mode in the game. On the plants' side, the player must gather moon to plant plants and defeat the zombies, while the zombies try to build up moon to raise zombies to invade the house. Both sides will have one producer (the plants will have a Sunflower, and zombies will have a special Moonstone) and five plants or zombies. The plants control six of the nine columns, while the zombies will only control three. Moon will fall on any of the plant's six columns like any other mode, and moon will fall on any of the zombies' three at the same rate. The mode can have up to 4 players (2 plants and 2 zombies). Each player gets one of each Boost for free to use during the fight, which are detailed at the bottom of the page.
There are three variants of Battle Ship available to play:
*Local Play: The host starts a lobby and gets a code. Other players can use that code to enter the lobby. There are no coin rewards associated with Local Multiplayer. Local Multiplayer also has Crazy Settings which can add to the fun.
*Online Play: Match with random players online and get coins if you win. There are two options available to choose for Online Multiplayer: 1v1 and 2v2.
*Private Play: Play against Easy, Medium, Hard, or CRAAAAZY!!!!! computers and get coins if you win based on the difficulty. There are two options available to choose for Online Multiplayer: 1v1 and 2v2. Private Play also has Crazy Settings which disable coin earning but can add to the fun.
==Zen Garden/Graveyard==
Zen Garden is a place to rest, relax, and enjoy the company of your plants. Tend to their needs to earn coins and maybe even listen in on some of their conversations. Graveyard is the zombie equivalent featuring, well, zombies (I know, massive shock).
<tabber>
|-|Zen Garden=
In Zen Garden (unlocked after completing level 30 in the Quest Boat campaign), players aim to obtain plants either through random drops (each zombie has a 1% chance to drop a sprout if they weren't unnaturally spawned in) or by purchasing them from the Shop. Sprouts grow into random plants after enough time, but if you put them next to 2 or more plants of the same type they'll have a larger chance to become that plant. Plants will randomly face left or right when grown, but this can be changed by tapping them.
There are 32 available spaces for Zen Garden plants in the main Zen Garden. Plants will periodically produce coins when they're happy, and eventually the player will be able to make a profit off of each plant even if it may take some time to do so. The Zen Garden is the player's main source of passive coin income, though it is only half as effective as one would imagine because there is both a Zen Garden and a Graveyard. Plants will need to be watered and then cared more intimately with bug spray, chocolate, or music later on. Plants can be moved around in the main Zen Garden by purchasing the Gardening Glove.
Zen Garden has lots of customization potential and there are a number of ways to make it look just the way the player wants it to. Inspired by the former PvZCC wiki cosmetic version of the Zen Garden, players can customize the Zen Garden in-game with Pots, Sceneries, and Environments as well as obviously the plants themselves. Pots change the way the pots plants go inside look like on an individual plant basis, Sceneries add a bit of a background effect behind or around the Pot to add some dynamic effects, and Environments change the visual design and theming of the entire Zen Garden. Those cosmetics can be obtained from the Shop.
|-|Graveyard=
In Graveyard (unlocked after completing level 30 in the Quest Boat campaign), players aim to obtain zombies either through random drops (each plant has a 1% chance to drop a trap if they weren't unnaturally spawned in) or by purchasing them from the Shop. Traps will attract a random zombie into the Graveyard after enough time, but if you put them next to 2 or more zombie houses of the same type they'll have a larger chance to become that zombie. When a zombie is added to the Graveyard, it comes with a special house that acts as its home base. Zombies will randomly wander around the Graveyard area but interactions are done with the stationary house. 
There are 32 available spaces for Graveyard houses in the main Graveyard. Zombies will periodically produce coins when they're happy, and eventually the player will be able to make a profit off of each zombie even if it may take some time to do so. The Graveyard is the player's main source of passive coin income, though it is only half as effective as one would imagine because there is both a Zen Garden and a Graveyard. Zombies will need to be and then cared more intimately with stinky spray, cheese, or airhorns later on. Houses can be moved around in the main Zen Garden by purchasing the Gravetending Glove.
Graveyard has lots of customization potential and there are a number of ways to make it look just the way the player wants it to. Inspired by the former PvZCC wiki cosmetic version of the Zen Garden, players can customize the Graveyard in-game with House Styles, Sceneries, and Environments as well as obviously the zombies themselves. House Styles change the way the houses zombies go inside and come from look like on an individual zombie basis, Sceneries add a bit of a background effect behind or around the House to add some dynamic effects, and Environments change the visual design and theming of the entire Graveyard. Those cosmetics can be obtained from the Shop.
</tabber>
==Shop==
The Shop is a very special place where you can buy AWESOME and WONDERFUL things using your coins. The further you progress in the Quest Boat, the more cool stuff you can buy - the stock changes depending on if you're in Paradise Palms, Riptide Rapids, Saltwater Beach, Jagged Jungle, or Coconut Sands. The Shop is a chill and relaxed place where you go to purchase awesome new things for your Zen Garden, cool cosmetic items for your plants, Boosts to help players power through particularly tricky Quest Boat or Shipwreck levels, and even purchase unique Super Plants or Heroes with strange and wonderful powers that can change the tide of battle.
===Boosts===
As mentioned earlier, Boosts are not meant to carry players through levels as there aren't really a whole lot of them. Boosts can be used to get through a level that's especially tricky for whatever reason or a Shipwreck level that's giving the player trouble. They're not a big part of the game in any form but they're just there if the mood strikes right. There are three types of consumable Boosts for plants and three for zombies.
Boosts can only be used in Quest Boat and Shipwreck levels, with a maximum of 3 total Boosts per level. No cheating with Party Yacht. Each player gets to one of each Boost for free in each Battle Ship match as mentioned earlier for extra spiec, but it's completely fair as you can't bring any more.
*Plants!
**Cherry Bomb: Deals heavy damage to zombies and zombie grid items in a 3x3 area. Costs $1000 each.
**Jalapeno: Deals heavy damage to zombies and zombie grid items in an entire lane. Costs $1000 each.
**Chilly Pepper: Freezes all zombies and zombie grid items in an entire column. Costs $1000 each.
*Zombies!
**Bungee Plumber: Instantly destroys all plants and plant grid items on the chosen tile. Costs $1000 each.
**Cakesplosion: Deals medium damage to all plants and plant grid items in a 3x3 area. Costs $1000 each.
**Chickening: Deals very light damage and stuns plants and plant grid items in three lanes. Costs $1000 each.
===Costumes===
Each plant and zombie has two different costumes that can be purchased from the Shop which functions like costumes in Plants vs. Zombies 2 if you can believe it. These costumes cost $3000 each, so that's a total of $6000 per plant, and they don't affect gameplay in any way. They're completely visual. I don't think it's been mentioned enough times that they're cosmetic items with purely cosmetic functionality that won't make the game any easier.
Costumes can be seen no matter what side the player is playing on. If the player has a certain costume equipped on a plant, for example, that plant will have the costume when they appear in Zombie Side levels. Costumes will also be seen on characters in the Zen Garden and in the Graveyard, but they are selected on an individual basis to allow for more variation and for different plants or zombies to have different costumes at the same time there.
===Zen Garden/Graveyard Items===
As mentioned above in the Zen Garden/Graveyard section, there are Pots/House Styles, Sceneries, and Environments that can be purchased with coins. The prices vary based on the quality of the item; there's some cheaper ones that aren't quite as exciting and then some much more expensive ones that come with many bells and whistles. There are different Sceneries and Environments for Zen Garden and for the Graveyard. All Zen Garden/Graveyard cosmetic items come with a randomizer function that changes them every time the player visits the Zen Garden/Graveyard. 
In terms of functional Zen Garden/Graveyard items, you can purchase the consumable objects that residents need like chocolate for plants and cheese for zombies, as well as new sprouts or traps to grow the population. Players can also purchase name tags that can be used on plants/zombies to give them a custom name in under 20 characters that will constantly display over their heads at all times. There is a button that can be clicked to turn them off if the player wants to take a screenshot or it's just overwhelming or something. The Gardening/Gravetending Glove can be purchased to move plants/houses around.
===Special Units===
There are special Super Plants and Heroes that can be purchased in the shop, with the prices listed in intimate detail on their respective pages. Super Plants are like upgrade plants from the first game, where they're more powerful but need to be planted on top of the base version. Heroes are similar, where you can only take one type into a level and only have one on the lawn at a time but they can be replaced and have activated abilities that cost moon and recharge after a certain amount of time.
When the player unlocks a plant, they unlock the ability to purchase its Super form. The Heroes gradually become available to purchase over the course of the Quest Boat campaign instead because they're not based on any particular zombie for the most part and there's not as many of them (they're more expensive to compensate for that, don't you worry).
==Trivia==
*The zombies using similar resources and features as the plants is a nod to how zombie-centric game modes were handled in the first game.
*Before this game came out, there were a number of different iterations of Island Quest over the years:
**Island Quest was first conceptualized as an open-world island adventure game with randomly generated environments.
**Island Quest was then changed into more of a puzzle game where plants and zombies worked together to defeat a common enemy. This idea of playing as both plants and zombies was used in the final version.
**Island Quest was changed to a tower defense game intended to be a recreation of Plants vs. Zombies 1 but was eventually canceled before being brought back to life a few years later (which is now!).
