“If u have problems on win11 with laggy or freezing launcher, just wait few minutes it will eventually work 100%, setting it to run on win7 mode and as admin wont hurt either. For all that say Cossacks 2 is better,…”

— a player, Steam review · 14 hrs played“Bugs, crash, bugs, crash, bugs, crash, bugs, crash, bugs, crash, bugs, crash. Multiplayer is completely broken.
