EvilVEvil is a cooperative first-person action shooter in which a team of villains battles other evil forces. Players pick from a roster of wicked characters, each with their own abilities, and fight through missions against hordes of enemies.

The emphasis is on fast, chaotic combat and teamwork, with players combining their characters' powers and weapons to overcome tougher foes, giving the classic co-op shooter formula a darkly humorous, villain-focused twist.
