The game is a third-person shooter featuring large play areas and waves of mecha and giant insects. Players control either a foot soldier (Storm-1) who uses conventional weaponry such as assault and sniper rifles, shotguns, and rocket-propelled grenades or a jetpack-equipped soldier (Pale Wing) who uses energy-based weaponry. Most of the game's missions are cleared by eliminating all enemies present, starting with giant ants on earlier stages and eventually progressing to giant lizard enemies. A number of vehicles such as a tank, helicopter and a hover-bike are available in some missions for players to board and attack enemies with. However, only the Storm-1 unit can use the vehicles.
