Mechanics

**Mechanics** are unique features in the game.

## Gamemodes

### Campaign

Campaign is the main gamemode in the game. There are currently 180 levels in the game. Early levels will have 5 waves, 7 waves, and then 9 waves. Levels can have a total of 10 waves, which, all waves have after the first few levels.

On levels 100 and above, levels will get drastically harder. Players will be hit with traps from Galaxy Skins, some enemies will have a constant shield that will only be deactivated for a short time, other enemies will have a freezing effect which will stop one from shooting for a few seconds, others can teleport, and some will shoot warheads when they die.

### Endless

Endless mode, true to its name, is a version of Campaign, but has endless waves. Boss will appear every 10 waves, but sometimes they will appear on a wave that ends with the number 5 (e.g. wave 45). Before bosses appear in this mode, the player can watch an ad that gives them a random booster to help them kill the boss. The player can refuse to spin it, and the wheel will not appear on every boss wave, but only the first few. Endless mode will end when the player reaches a certain milestone for waves required (e.g. wave 50), or when they die. Players in endless can start with boosters, just like in Campaign, and they will have 3 lives. Loosing one will halve one's power/bullet level, unless if they have the expert item Power Saver on their ship they were using when they lost a life and it activated.

### Boss Mode

Boss Mode is a gamemode where the player only fights bosses. They cannot start with boosters (including starting with different spaceships) and will start at max bullet power. There are currently 45 bosses. Bosses will appear every 4 after the last one (e.g. level 4, 8, 12, etc.).

There are currently 6 different types of bosses:

* Pattern Bosses - Are bosses that follow a specific pattern that does not change. They will not make any sounds will charging and using attacks. Most pattern bosses will move left and right slowly, while some others will move randomly across the screen.

* Random Bosses - Are bosses that do **not** follow a specific pattern and will use attacks randomly. When using or charging an attack, they will make sound effects. They will also turn red when damaged. Upon defeating a random boss, it will blow up into pieces. They will also move left and right.

* Multi-part Bosses - Multi-part Bosses are the same as random bosses, but have different parts the player can destroy before actually killing it. Instead of moving left and right, they will move randomly across the screen. Destroying a part will make the boss unable to use that said part to damage a player (Some bosses have exceptions, such as Apache). The main part has more health than the other parts, and destroying it will kill the boss even if there are other parts that are not destroyed yet (Again, some bosses have exceptions, such as Bello).

* Dual Bosses - Dual Bosses are exactly what it sounds like; the player has to fight two bosses at once. They are currently the least used boss type, being used 2 times (Twins Culi and Gemini). Some of them follow a pattern (Twins Culi) and others can do different attacks at once (Gemini). They can also be any type of boss (Twins Culi is a Pattern Boss, and Gemini is a Multi-part Boss). There are technically 3 dual bosses in the game, with the third one being Deathmire (The mini boss version of Metal Assassin)

All of these boss types are also known as Big Bosses.

* Mini Bosses - Are bosses that are recreations of already existing Big Bosses. They will move around the map a lot more often than big bosses, and have no limit to where they can move. This means they can go to the bottom of the screen, which big bosses can't do. There are 20 mini boss levels, and each level will have the bosses from the levels before it. The player will also be hit with traps.

* World Bosses - World Bosses have a extreme amount of health and will appear every Friday. If one player damages a boss, that damage will damage it on every one else's bosses. (e.g. If a World Boss has 20,000,000,000 (20 billion) health and someone deals 1,000,000,000 damage to it (1 billion), the health of the World Boss will be at 19,000,000,000 (19 billion) health for everyone else currently playing.) Players have a limited number of turns. Every 30 minutes, the player will get an extra turn. They can also sometimes watch an ad to immediately get a turn, or they can pay 1K gold per minute left on the timer (Ex. if a player has 24 minutes left, they will have to pay 24,000 gold (The cost will always be rounded down)). Players will get prizes depending on how much damage they do, starting with gold and ending with Epic Chests. There are currently two World Bosses:

* Eron Destroyer (15,000,000,000 (15 billion) health)

* Shadow Cobra (20,000,000,000 (20 billion) health)

### Hero

In Hero Mode, there are different planets the player can choose from:

* Terra

* Biotox

* Hydron

* Void

* Hellion

Each planet is harder than the last. Players have 30 seconds to finish each wave, and if they don't, all alive aliens will be buffed, and they will be given a special ability. In some waves/levels, objects will be thrown from the left and right side of the screen. (e.g. In Terra, they are meteorites, and in Void, they are chunks of ice.) On the last wave, when there are only a few aliens left, they will travel to the center of the screen and will perform a "ritual", and will spawn a boss. This can be prevented if the player uses the explosion made when they use the second life of the Legendary spaceship, which will kill the aliens before they can spawn the boss. The 30 second timer will disappear during the boss fight. They can also just kill the aliens very fast, givng them no time to summon the boss.

### PVP

PVP is a gamemode where players will race others and complete waves before their opponents do. There are five different PVP gamemodes, which are 1v3 (aka. 1v1v1v1), 2v2, 1v1, Survival, and Arena. In solo and arena, they have 3 lives in each match. Losing one will halve their power/bullet level, unless if they have the expert item Power Saver on their ship they were using when they lost a life and it activated. However, in arena, they have 3 lives. Losing a match will take away 1 life, and if they lose all 3, they are out. In all modes (Except Survival), the first team/player to reach a total of 50 waves will win. They will also win if their opponent(s) dies, or if they get a 6 wave lead ahead of their opponent(s). Players can also use galaxy or predator skins to attack their opponents, giving them a better chance to win.

## Spins

A player can spin a wheel that gives them prizes. They will get a free spin every hour. They will have to watch an ad afterwards, and then they will have to pay 6,000 gold per spin. A player can spin the wheel a total of 10 times per day.

## Chests

Chests can be opened by the player for valuable items, such as evolve stones and legendary tokens. The player can open chests to level up said chest (except the Hextech Chest). The higher the level, the better the rewards. There are currently 3 chests:

* Blue Chest (Cost: 7 Crystals)

* Epic Chest (Cost: 20 Crystals)

* Mythic Chest (Cost: 50 Crystals)

* Hextech Chest (Cost: 1 Hextech Key)

## Matrix

Matrix is a system where the player will get a random item from the 3x3 grid. The cost is a Matrix Ticket or 20 crystals. These items can be pieces of Expert Items or ship skins. They can also be evolve stones. There is also a separate button which does 10 turns in quick success, as a QoL option. However, the player will get a 10% discount for crystals needed, meaning doing 10 turns will cost 180 crystals if they do them all at once.

## Traps

Traps will sabotage a player's opponent(s) in PVP. They can be used with Galaxy and Predator Skins. They will also appear in Campaign mode past level 100. There are currently 18 offensive traps and 1 defensive "trap", with the defensive one being Predator Legendary.
