If GSC Game World has a motto, I think it should be 'the mad lads are actually doing it.' Not only did the Ukrainian studio release a killer (albeit, admittedly, somewhat on fire) game with Stalker 2 under some of the grimmest imaginable conditions last year, it's now decided to go ahead and just upgrade the entire Unreal Engine 5 basis the whole damn thing runs on.
So says Stalker 2's roadmap for Q3 and Q4 2025, released yesterday. Right now, Stalker 2 uses Unreal Engine 5.1, but top of GSC's list of bulletpoints for the year to come is "Engine update to Unreal Engine 5.5.4 (for optimisation)." That's not the bleeding-edge version of Epic's engine—that would be UE5.6—but it is a recent one: it only hit last March.
