Player characters can roll and take cover to avoid attacks. This ability was described by a Visceral Games developer as essential, as it "felt dumb/terrible not to have it" and that they have been "making Isaac more responsive", as they "want the horror to come from the terrible things that happen in the game; not from the horror that something is moving slowly towards you and you can't shoot it because the game controls like a piece of crap. " The cover system is also described as "organic" in nature; for example, the player does not need to "walk up to certain tagged things and press the cover button; Clarke . . . just does the action that is appropriate for the given situation. "
