Immune - True Survival

Players try to survive in a wasteland, alone or with friends, while facing threats including mutants, bandits, wild animals, and soldiers.

Craft weapons, clothing, and tools, then build a fort to defend yourself and your loot. You can also plant and harvest food or go fishing.

Progress through XP, ranks, and missions, with optional player-versus-player or player-versus-environment play. Other listed systems include health conditions, medicine, vehicles, trading, and character customization.

The supplied reviews mostly focus on the game being discontinued and its servers being unavailable, with several players saying this left it unplayable. One reviewer mentions achievements and collectible cards, but the reviews express little clear enjoyment of the gameplay itself.
