+Summary:Multiplayer crossplatform action game with destructible procedurally generated worlds
+Description:
+Each player controls a tank, opens fire from the turret and navigates between the terrain features.
+Explosions from turret fire and tank destruction have different forces and destroy the terrain.
+Each tank needs 4 hits to be destroyed.
+Destroyed tanks drop health power-ups which can repair other tanks.
