BORDEAUX, France – Aug. 31, 2026 – The much-anticipated closed beta for Frostrail, the brutal co-op survival FPS from Barotrauma developer FakeFish and publisher Shiro Unlimited, launches today on Steam as part of Steam’s PvE Survival Crafting Fest. To join the playtest for the top 100 wishlisted game, sign up on the Frostrail Steam page.
Brave the bitter cold of a post-apocalyptic, unending blizzard, traversing by way of locomotive. Climb aboard a train alone or in a team of up to four and set out across the wasteland. Stop to scavenge ruins, secure vital resources as well as other much-needed supplies, and survive day-by-day.
Explore the remnants of villages, rundown mining camps, and deadly underground vaults to gather food, materials, and powerful weapons before racing back to the train before the cold claims you. Remain ever-vigilant: the blizzard’s bite isn’t the only threat to manage. Ravenous creatures called Revenants stalk the wasteland, attacking unsuspecting adventurers. Repel their violent hunger with an arsenal of melee and ranged weaponry in intense FPS showdowns.
Engage with deep crafting systems aboard the locomotive, turning scavenged materials into upgraded arms, armor, and upgrades to the train itself. Create research stations, medical bays, and even new cars to turn the train into a mobile fortress while progressing deeper into the wasteland
“Throughout development, community feedback has been central to making Frostrail the best game it can be,” said Ez Jämsen, Lead Designer at FakeFish. “With the launch of today’s Closed Beta, we’re eagerly awaiting the next batch of survivors and excited to hear their feedback as we prepare for our Early Access launch later this year.”
Frostrail will launch on Steam Early Access for Windows PC in Q4 2026 with English, Spanish, French, German, Russian, Polish, Portuguese – Brazil, and Simplified Chinese language support.
