Stalker 2 says to hell with it, let’s just update our entire Unreal Engine implementation in new roadmap for the rest of the year

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.
