Survivalist Invisible Strain

Survivalist: Invisible Strain is an open-world zombie colony sim often compared to State of Decay, Project Zomboid, Rimworld and Kenshi. The setting is ten years into a zombie infection, with long-established settlements collapsing one by one for unknown reasons. Survivors flee to remote areas hoping for safety, and you arrive as another refugee carving out a new life.

All living characters have names and personalities. They remember your actions, gossip among themselves, eat, sleep, work and fight independently. Recruit followers by making them like, respect or fear you. Manage their morale and relationships: they get depressed, fight each other, sometimes kiss and make up. Build a settlement around your chosen home with farms, hunting, walls and crafting stations.

Combat is hybrid: directly control characters in third-person action view, or assign orders from RTS overhead view. Target enemies' legs to slow them or heads for damage, dodge or block in melee, equip ranged or close weapons depending on situation. The Invisible Strain is the new wrinkle: infected NPCs seem normal as they infiltrate your group and spread the virus before turning. Story mode introduces the world and mechanics with a hand-crafted story; Sandbox mode generates random worlds. Up to 4-player online co-op supported.
