Mutant Storm is a top-down, dual-stick shmup, similar in some ways to the classic Asteroids game. You pilot a tiny ship that careens around single room, vertical plane stages and you must blast all the encroaching mutants while dodging their incoming fire. You can pick up power-ups to boost your abilities. You can play offline with either one or two players. There is no online multiplayer. Adventure Mode is the campaign in which you advance through the levels. Tally Mode is a quickplay mode that requires you to try and rack up the largest number of points on a given stage. You can add personal music tracks to the gameplay.
