*Main article: Alien Traits*

Alien Traits are special perks that can change how The Host plays the game, either altering their existing abilities/mechanics, or adding new ones.

Alien Trait's effects compound onto each other, and can make certain combinations cause wildly different/new effects or changes to gameplay.
