Can you survive in a world that has been overrun by zombies? Survivalist: Invisible Strain is an RPG and base builder set in a post-apocalyptic world 10 years after the zombie virus hit the planet. For some mysterious reason, the once-safe havens of the world are collapsing, and you must escape to the wilderness to build another community you can call your own.

Build a new settlement in a randomly generated world and populate it by recruiting other survivors. Each one has their own personality and abilities, and will react to you depending on how you treat them. You must feed, clothe, and protect them from raiders and zombies alike.

Engage in dynamic combat where you can target your opponent’s body parts to cause debilitating effects. Take note that both you and your opponents can dodge attacks. You may also level up skills like Archery, Firearms, and Hand-to-Hand combat to keep up with more dangerous foes.

You must do everything you can to survive, if it means planting crops, scavenging in the wilds, raiding other survivors, and of course, killing zombies. Life is hard in the post-apocalypse, but you must make do somehow. Do you have what it takes to stay alive in Survivalist: Invisible Strain?
