Mighty Mighty Missile! for the SegaCD is an unlicensed clone of ChuChu Rocket!, which was originally released on the Sega Dreamcast. The game closely mimics the presentation and gameplay of Sonic Team's earlier releases, including stages adapted from both the Dreamcast and Game Boy Advance versions.
The mechanics of Mighty Mighty Missile! are largely identical to those of its parent game. Players have indirect control over the Mousers (the equivalent of ChuChu Rocket!'s ChuChus), whose trajectories must be modified through the placement of arrow tiles. The goal is to direct the Mousers past a variety of obstacles, including the Catz (KapuKapu) in their path to the missiles (rockets).
Arrows are placed using the 
button and a direction on the control pad; they can be removed by pressing the button again. When playing in Puzzle mode, the 
button is used to begin the stage and also to enable fast forward playback.
Game modes
- Original Game: a frenetic, multiplayer game in which up to four players compete to rescue the greatest number of Mousers. Equivalent to "4-Player Battle" in ChuChu Rocket!
- Puzzle: a single player mode where arrows must be set before play begins. All Mousers must reach the missile in order to complete the stage.
- Catz Soccer: this unlockable multiplayer mode does not feature Mousers at all; rather, all players start with maximum score and must direct Catz to their competitors' missiles to reduce their scores. The player with the highest score after three minutes wins the round.
- Snake: an unlockable single-player mode which recreates the classic snake game, as featured on Nokia phones, using Mousers and missiles in place of the snake and fruit.
