Nemesis: Retaliation is the third installment of the Nemesis horror board game series. Like the first two, it is designed as a standalone game.

This time, players take on the roles of highly trained marines, entering the alien nest with strict orders and the most advanced tools  available. But will they be well-prepared enough to face the unrelenting horde that awaits them? In Nemesis: Retaliation, players must survive against overwhelming odds and the possibility of betrayal at every step.

Some of the new mechanics are:
Reworked health system
New character actions
Modular map system with special exploration cards
Item management track
Individual objectives allow for hidden traitors
