Ice Punks (battle royale)

Ice Punks is a single-player 3D-action battle-royale game set in a post-apocalyptic future of nuclear winter. The main feature of the game is the destructible level surface. You can blast the ice with well-crafted puck-bombs. And everyone knows the water is dangerous.

Controls: WASD, LMB - Hit, RMB - Block, Shift (Hold) - sprint, G (Hold) - grenade. Sprinting heals. Also if you sprint long enough and bump into someone, you can push him forward. Right into the water.
