If Worms joined the army, you'd essentially get this game created by a one-man army of a developer in Michał Marcinkowski, a Polish computer scriptwriter. The multiplayer and free-to-play shoot-em-up is the perfect remedy to a hard day at work, allowing you to take our your office frustrations out on a battle arena full of rocket launchers, machine guns, and grenades. In the words of one wise Rambo: "Sometimes, killing is as easy as breathing."
