Frostrail is a brutal open-world survival FPS from publisher Shiro Unlimited and developer FakeFish, the team behind Barotrauma. The game is set to enter Early Access on PC via Steam in 2026.

Set in a frozen post-apocalyptic empire twisted by an ancient pact with the Void, Frostrail casts players as Penitent Gardeners—soldiers of mercy and judgment—riding aboard a massive, steam-powered train across a land haunted by revenants and unspeakable horrors. Your train is both sanctuary and salvation, the last moving stronghold against a world lost to cold and corruption.
Players can go it alone or join forces in co-op to explore deadly ruins, scavenge scarce resources, and upgrade their train into a mobile fortress. Managing heat, fuel, and firepower becomes essential as you push deeper into the icy unknown, where every step away from your engine is a gamble with death.
With its blend of first-person combat, scavenging, crafting, and base-building on rails, Frostrail challenges you to not just survive the cold—but to outrun it. Every blizzard, bunker, and abandoned stronghold hides both reward and ruin. The frost is always watching. And it never stops hunting.
