Extinction

Extinction is a game mode featured in Call of Duty: Ghosts. The game mode features up to four players fighting Cryptids (ancient creatures that have existed before the dinosaurs) in outbreak sites where the Cryptids have overrun the area. Players have objectives, which are to destroy cryptid Hives and complete Challenges. Players also earn money by killing cryptids, destroying Hives, or searching Search Piles. The money earned from these can be used to purchase additional weaponry placed throughout the map (similar to Zombies) and use abilities selected pre-game. In addition, players are able to customize their player, much like in multiplayer mode.
The Traps that can be used against the cryptids are the electric fence and fire traps. The traps cost money to set and only last for a short period of time. The traps do not have a cooldown time and can be used as often as the player wants provided they have the money needed.
There are four classes for the player to choose from, Weapon Specialist, Tank, Engineer, and Medic. For each class there is a specific set of unique abilities/perks that the player will be able to utilize for themselves or their team. There are also loadout slots that players can choose different options from including: Pistol, Ammo Type, Team Support, Strike Package and Equalizer, the player also passively has On the Go and Resilience. Once the player completes level thirty, they will automatically prestige, allowing them to equip an additional Relic, once per prestige. The mode is not infinite round based like Zombies, but has an ending and is much more linear.
If a player receives enough damage they will fall to the ground (frequently referred to as "down", due to its similarity to the same action in Zombies). During this period of time the player is still able to use their pistol. However, another teammate must revive the fallen teammate or they will bleed out and die. When a player dies they will spectate another player and a dog tag will appear where their body was located. Nevertheless, it is still possible for another player to revive the dead player at their dog tag. In solo, at the start of the game, the player can be downed once and revive themselves after a couple of seconds, but next time they will directly die. However, when a barrier hive is destroyed or the player proceeds to the next section of the map, the player receives an extra chance; this means that the player can be downed a maximum of three times in a single game before dying. However, in Exodus, each generator finished adds an extra life, allowing for a total of 6 (or 7 if playing solo) self-revives to be collected.
Much like with Squads, player progression is separated in online and offline. This means that any progress made playing locally won't transfer to online play, and vice versa. Unlike Squads however, only the basic equipment is unlocked from the start in local mode, and everything else must be earned by leveling up and prestiging. Online progress also carries in between consoles of the same family.
When playing in Split Screen mode, progression for the second player is carried only in online play through their Call of Duty accounts. In local mode, the second player always starts at level 1, regardless of wherever they're logged in or not. 
The maximum amount of money a player can carry is $6000 ($3000 with the Smaller Wallet Relic, $8000 with the +4 Engineer upgrade or $4000 with both). The player will receive money after a Hive is destroyed, based on their score earned while it was being destroyed. A supply drop of $3000 ($2250 with Smaller Wallet Relic) will be dropped after a Barrier Hive is destroyed. Also, a $2,000 supply drop will spawn in after the first fight with the Breeder in Nightfall, and $3,500 will be given to players once an Ancestor has been killed in Exodus.

==Ranks==
In Extinction, there are 25 Prestiges. Originally, there were 5 prestige levels, but with the release of every map pack, 5 new prestiges were added. The player must reach and complete rank 30, which will earn the player the next prestige level and automatically reset them back to rank 1. However, players will retain all unlocks regardless of prestiging. At prestige 25, upon completing rank 30, the player will reach rank 31 to show that they have earned the maximum amount of experience. However, players stop unlocking anything after hitting 10th prestiege, which unlocks the 10th and final relic slot. After that point, players will still level up, but they will only be earning more Teeth.

==Weapons==
==Relics==
The following five relics were released initially with the game:
*Take More Damage - Players take more damage when injured. (Approximately 25% increased damage)
*Pistols Only - Weapon purchases are not allowed. (Players also cannot pick up free customized weapons found in lockers or the Venom-X)
*Smaller Wallet - Earn and carry less cash. ($3000 Maximum cash and 75% money earned)
*Mortal - No Class selection available.
*Do Less Damage - Inflict less damage against the aliens. (Approximately 33% less damage dealt to all aliens)
The following five relics were released along side the third DLC pack Invasion for the map Awakening:
*Fragile - Slow health regeneration, no regeneration while sprinting, and falling damage is enabled.
*Stand Your Ground - Move slower. No reloading while sprinting.
*No Machines - No Equalizers or Strike Packages available.
*Limited Ammo - Ammo refills and weapon pickups will give you less ammo.
**Ammo boxes (no matter the type or skill level) will give 25% ammo which is about 1 mag for an LMG, ~ 2-3 mags for rifles and SMGs, ~1/4 max ammo for pistols.
*Earn Your Keep - No Ammo Type and Team Support items available and no scavenging, crafting, or pickups from deployed boxes.
**Players with this relic equipped can still take Ammo from Support drops, the +4 Upgrade for Regular Ammo makes box Regenerate Ammo to all players within a 20 ft Radius of it, which also applies to Players with 'Earn Your Keep' active. This also applies with Cryptid Slayer Ammo, as it too regenerates.
**Players cannot open lockers, even if they have the "Start with a Locker Key" armory upgrade.
**If the Player is revived after completely bleeding out, they are able to take ammo from a team deployed box once after being revived.
*If the Player has Pistols Only and Earn Your Keep active, they can acquire Ammo from any of the buyable weapons around the map. It is titled on the screen as "Pistol Beast" and costs $1500, the player will then receive maximum ammunition, but considerably less if Limited Ammo is also active.
==Armory==
As of April 3, 2014, there is an upgrade system, using "Teeth" () to purchase upgrades in the loadout menu, these upgrades will carry through each game.
Spend Teeth in the armory to purchase upgrades for classes and equipment. Earn Teeth by Completing Extinction missions. Bonus Teeth are awarded for using relics, playing Hardcore mode, or helping other players complete a mission for the first time.
Teeth are also earned by killing 300 Cryptids (regardless of difficulty), achieving ranks 2, 6, 11 and 21 for the first time, and prestiging. Players are also awarded 2 teeth for successfully completing 10 challenges in one mission and 4 more for completing all challenges without failing one. Players get 4 teeth for a platinum escape, 3 for gold, 2 for silver, and 1 for bronze. Players are also awarded one tooth per relic used if the mission is completed.
There is also a 'Bonus Pool' which contains three Teeth that can be obtained by completing the first area of a map. The bonus pool refills every seven days. A patch changed this to one bonus tooth each day.
Contrary to popular belief, escaping without ever being downed or repairing the drill do not grant bonus Teeth. There are no other methods of earning teeth other than the ones mentioned above.
Teeth can be farmed in large amounts by doing a Harcore 10-relic run, but this is extremely challenging (if not almost impossible) and requires amazing teamwork between 4 players.

==Difficulty==
An update for the mode included several new difficulty modes for the game to be played at.
Casual: The number of Cryptids that appear are reduced by 50%, their health is also reduced by 50% (Scouts can now be killed with a single melee attack; Rhinos take up less than a single LMG magazine to be taken down). Cryptids are not as aggressive as before the patch, players will take less damage as a result. Cryptid damage to the drill is also reduced by 50%, so the frequency to repair it, or to keep it above 50 health for the challenge, is easier. Players also spend less money by having to use their abilities less often (the prices are still the same, it's the frequency of using them to resupply/re-armor that allows players a full bank most of the time in this difficulty). Playing on Casual, however, does not count towards leaderboard placings; scores won't be posted, escapes will not count, and teeth for the armory are only earned via bonus pool, killing a large number of Cryptids, and Prestiging. But, the number of Cryptids the players kill will still count towards the 10,000-weapon-kill operation and still earn the Multiplayer patch. Additionally, escaping while using a Relic will also still count towards the background challenges. A recent update made a casual playlist online, with rotating maps.
Regular: This is the default difficulty setting, and before patches, was the only difficulty setting. Playing on specific mission playlists online defaults to this setting.
Hardcore: The crosshairs on the player's HUD is removed, the cryptids are more aggressive and skill points are not earned for destroying hives. However, skill points will still be given out for entering new areas. Ricochet friendly fire is also turned on. Substantially more difficult enemies appear to spawn much earlier on. Players tend to be faced with Hunters on the very first hive. Specifically on Point of Contact, within the first area, players come face to face with large numbers of Meteors/Seekers. A recent update made an online hardcore playlist, with rotating maps. Extra score is given in Hardcore compared to Core game types, and money payouts after a hive/obelisk/generator are increased in size. Each map's leaderboards have a dedicated Hardcore section that can be viewed by toggling a setting when viewing a map's escape leaderboard, both for solo and co-op play.

==Trivia==
*A prototype for a sequel to Extinction was developed, featuring base building, RTS elements"Extinction 2 would have been AMAZING! That prototype we built had so much promise!" - Lee Ross, Twitter"Yep the video is cool. Base building baby! A little RTS mechanics in the mix" - Brian Bright, Twitter, and combat classes"Fully functioning prototype map with combat, base building and combat classes. 😎" - Lee Ross, Twitter. The story revolved around humanity being an extension of the Cryptids, with Samantha Cross becoming an antagonist"Samantha was going full fucking villain. Cryptid types were expanding massively. I would have taken that story to a place where we explained that we are merely an extension of the Cryptids. 😎" - Lee Ross, Twitter. The sequel was ultimately scrapped as Infinity Ward didn't want "aliens" in a game taking place in space and was replaced by a Zombies mode for Call of Duty: Infinite Warfare."To be fair, if we made Extinction 2 there would not have been IW Zombies. The studio was nervous about taking COD to space and didnt want “aliens” in it, even though the cryptids were not aliens." - Brian Bright, Twitter
