Incoming is a 3D shooter game that puts you in the middle of a battle against aliens. The story begins with a surprise attack on Earth's moonbase and then spreads to different continents as you try to defend your base. Your mission is to stop the alien invasion by controlling various vehicles, including a harrier jet and an alien fighter, and eventually leading the counterattack on the moon.
The gameplay in Incoming is fast-paced and action-packed. You can play through arcade mode as a straight shooter or take on specific missions that require you to control different types of vehicles, such as tanks, helicopters, or enemy aircraft. The game also features two special modes: "action" and "action-tactics", which give you limited control over other friendly units.
