SPECIAL ATTACK: Tentacle Strike

Press and hold the Power button to charge an attack. Once charged, tap the Attack button.

Mutation Rate: Your power expands as your Mutation Rate grows. At Mutation Rate 2, Tentacle Strike can destroy pallets and breakable walls. At Mutation Rate 3, Tentacle Strike's range and movement speed increase when it's fully charged. The T-Virus icon displays the current Mutation Rate.

SPECIAL ENEMY: Zombies

If a zombie hits a Survivor, they inflict them with the Contaminated effect. If already Contaminated, their health will be damaged.

Zombies can be destroyed by a Tentacle Strike to increase your Mutation Rate, and Survivors can destroy them with pallets. Destroyed zombies eventually respawn.
