This game is a comic relief in the otherwise tragic war in Ukraine. It uses multiple popular jokes, starting with the famous phrase about the russian warship.
It’s a top-down shoot ’em up game with tower defense elements. You start at Zmiinyi Island (Snake Island) in the midst of the Black Sea where you find yourself attacked by multiple waves of enemy ships. You need to defend the island, gradually growing your arsenal with new weapons, turrets and upgrades. If you succeed to defend Zmiinyi you can proceed to free other territories and try to win the war.
