When a virus makes robots go rogue, you and your squad are sent in to take back control of the situation by taking on endless waves of increasingly violent synths. Go now mercenaries! Execute .synth_protocol.

.synth_protocol is a goofy cooperative first person wave shooter, where you team up with your friends to take on endless hordes of zombie-like robots, synths. Progress to unlock new areas and cosmetics, or just mess around and have fun goofing off with your friends.

Online co-op from 1 to 4 players with proximity voice chat.
