What is Anomaly Protocol?

This horror game supports solo play or online co-op for up to four players across a ten-day cycle. You gather lure stones in irradiated underground levels, where unkillable entities force you to run or hide. Above ground, you turn stones into bait, lure zombies to kill and sell, and spend the proceeds on better equipment.

For you if...

+you enjoy risky supply runs and careful spending decisions
+you like cooperative horror with room for messing around

Not for you if...

−you want selectable difficulty and a detailed tutorial
−you prefer fighting every enemy rather than running and hiding
