How to earn MW3 Altered Strain rewards

Earning rewards during the Altered Strain event is slightly different from other in-game events. Players need to collect DNA samples from fallen players and caches to earn rewards and different effects to use in the Mutation mode.

Score kills and open caches to earn plenty of DNA samples in exchange for all kinds of rewards.

MW3 Altered Strain Augmentations

Alongside the rewards, the Altered Strain event allows players to unlock Augmentations to use in Mutation matches. Check out the full list of Augmentations and their abilities below:

  • Galvanized: Temporary damage reduction from explosives
  • Repocket: Kills scored with abilities may replenish tactical ability
  • Attuned: Cost to earn Mutant Juggernaut is reduced
  • Flop Shot: Diving from surfaces creates a small explosion
  • First Strike: Faster cooldown of first ability used after respawning
