Survivalist__invisible_strain....

is an open-world colony-building survival simulation that blends the deep mechanics of RimWorld and Project Zomboid with the third-person action of State of Decay . Released from Early Access in early 2025, version 1.0 features a procedurally generated world where your goal is to build a settlement, recruit survivors, and survive the "Invisible Strain"—a virus that allows infected individuals to infiltrate your group without showing symptoms.
