Description (written by the developer; not a statement by this register)

Operation Aberration is a co-op survival game inspired by the likes of Killing Floor and A-888: Project Creedbreaker. You're deployed into a containment zone with the goal of using a vast array of weapons, skills, and tools to survive. Activate drills to stay in the containment zone longer and push back against the ever-growing hostility of the anomalies. Remember, you're fighting for the fate of humanity. (Controller is supported, but Keyboard is preferred!)
