The game involves piloting VTOL aircraft, pretty they are jet powered helicopters without rotors. The player can choose to view the action from a variety of first or third-person perspectives, including views from within the cockpit, a variety of "chase" perspectives, including directly from above the craft (for use when bombing). Combat in G-Police involves both dogfighting with other aircraft and dropping bombs. The player is often required to "scan" suspect vehicles to determine if they are criminal or hostile. The game's aircraft comes with numerous weapons which are upgraded as the player progresses to more difficult levels. An improved version of the basic "Havoc" aircraft (the "Venom") is also available later in the game. Missions include seeking out and destroying enemies, escorting friendly ground units, preventing smuggling and bomb disposal. The player receives updates and new instructions as the mission proceeds. The main game mode features 35 missions and an additional training mode. Most of the game's mission take place in urban "domes" filled with large buildings; some, however, take place in the "outer domes", with other themes such as agrarian settings.
