Grimm Survival

"Alright, looks like you guys got yourselves in a mess. Well all I can tell you is to just hold off as long as you can, I'll see if Hen- I mean your Special Operations Command can send you help."

- Mr. Tachibana Grimm Survival Introduction

Grimm Survival is a game mode introduced in Extinction Season Two for Call of Duty: Extinction. It is essentially Survival Mode from Call of Duty: Modern Warfare 3 and is inspired by Survival from Call of Duty: Black Ops II Zombies. It also returns in Call of Duty: Age of Extinction with additions and improvements.

Grimm Survival allows no pre-selected Create-A-Class loadouts, Specialized Weapon Variants, Classes, Team Support items, Strike Packages, or Equalizers. In Extinction, Special Forces General Christina Foley is the commander/announcer. In Age of Extinction, General Richard Lawson replaces Foley as the commander/announcer.

There are differences between the Extinction Grimm Survival and the Age of Extinction Grimm Survival.
 * In Age of Extinction Grimm Survival, the Weapons Crate is not available due to the Loadout system
 * In Age of Extinction Grimm Survival, the Urasi are encountered in normal Waves
 * In Age of Extinction Grimm Survival, Difficulty is dependent on the location of the map that's being played

Scoring
In Grimm Survival, players will earn Points for killing Grimm and will contribute to the Team Score overall. Points are used to purchase new weapons and Specialized Weapon Variants from the Weapons Crate, and make purchases within the Equipment and Command Crates.

Points awarded for each Grimm killed:
 * Warrior — 50 Points
 * Gladiator — 100 Points
 * Scorpion — 150 Points
 * Aggressor — 300 Points
 * Vindicator — 25 Points
 * Bruiser — 200 Points
 * Stalker — 100 Points
 * Apparition — 500 Points
 * Guardian — 1000 Points
 * Urasi — 1500 Points

Special Waves
Much like Zombies, players will encounter "Special Waves" which features enemies not normally encountered by players. These enemies are new Grimm created specifically for the Special Waves.

The new Grimm encountered are called the Boarbatusk which, much like the Rhino, will perform a "rolling" attack at players that deal high damage and usually staggers players for a split second and leaving them vulnerable for that split second. Like the Hellhounds Special Waves, the last Boarbatusk will drop an ammo case containing ammo for all players. Killing a Boarbatusk awards 200 Points.

However unlike the Hellhounds where after reaching a certain Wave, Hellhounds would begin to regularly spawn, the Boarbatusk will not; remaining only as an encounter for the Special Waves, and will appear every 6 Waves and will get increasingly more powerful each time.

Boss Waves
Added in Age of Extinction, players will encounter Boss Waves which will have players fighting a Boss. Every 9 Waves, players will encounter either a named Boss or a High-Value Tier Boss. Once defeating a Boss, players will be rewarded with 8000 Points; the highest amount of Points players can earn.

High-Value Tier Bosses will all have the same default fighting style of the Grimm they are; High-Value Tier Bosses will vary between all types of Grimm, even Warriors and Vindicators. However, named Bosses will have a unique fighting style and special attacks; these Bosses will look radically different than other Grimm.

Challenges
At the start of a Wave, players will be given two Challenges as another method of gaining Points aside from killing Grimm. These Challenges are in Tiers with the first being the easiest. Once completing a Tier, players are awarded Points, and sometimes a Weapon as a reward.

These Challenges, if not completed, will carry over to the next Wave and two new Challenges will be assigned if completing them. These Challenge Tiers will also be randomized.
