Extinction is a four-player, co-op game mode featuring a unique blend of fast-paced survival gameplay, base defense, player customization, and class leveling rounding out this robust new Call of Duty: Ghosts game mode. Teamwork and communication are essential when playing Extinction, as your team faces an inhuman menace that has overrun an isolated Colorado town, and you must eliminate the threat via any means necessary.
 
Your Squad
At the start of the game, each member of the team chooses from one of several custom character classes - medic, engineer, tank, or weapon specialist.
 
As the team battles through the streets of Caldera Peak, players earn currency that can be used to purchase a variety of upgrades and character abilities. The team can also scavenge for special equipment and weapon mods left behind by previous, unsuccessful, military forces.
 
Your Objective
Extinction’s fast-paced survival combat features a series of intense base-defense scenarios. The team members must work together to hold off waves of alien attackers until each alien hive can be neutralized. The team can fortify their positions using a variety of military-issue and improvised defenses: electrified fences, fire traps, shock puddles, heavy weapon turrets, and drones.
 
During each game session, players will also earn Skill Points that can be used to buff their loadouts, enabling players to develop highly-specialized skill sets over the course of a single game. No two games are the same as the moment to moment upgrade decisions can dictate the strategies of the team. Team Challenges also allow teams to earn extra Skill Points, buffing their capabilities even further.
 
Your overall objective is to destroy the alien threat with the help of a nuclear device. Once the team finds the nuke, they must arm it, race back through the town to escape on their chopper - mad dash race through an insane gauntlet of alien terror.
 
The Enemy
Extinction features a variety of new alien enemies, from wall crawling Scouts, ferocious Hunters, devious exploding Seekers, leaping and spitting Scorpions, and massive armored Rhinos that can decimate an unprepared squad in a matter of seconds.
 
Hints and Tips for Success
Players can equip up to four found attachments on their weapons, find flares, trophy systems, special ammo, and even a Hypno-Knife that can brainwash enemy creatures, transforming them into savage allies for a limited time.
 
Extinction’s new Combat Spend system also offers access to a wide range of offensive, defensive, and support equipment bonuses that can turn the tide of a desperate battle. It will take communication and cooperation to defeat the horde; deploying support items and sharing them amongst the team - from armor, to explosives, to incendiary ammo - is a key to success.
