G-LOC: Air Battle is a simulation game where you play as a UN loyalist tasked with shooting down enemy planes and warships. The world has been taken over by the Citizens Defence Force, which has confiscated all military assets from the United Nations. Your mission is to take back control and keep the world at peace.
The gameplay involves flying through 8 stages, each with its own sub-stages on land and sea, all with strict time limits and targets to hit. You'll be armed with 10 missiles and standard weapons, and your plane can withstand a few hits before being destroyed. As you progress, you'll gain access to better planes and increase your rank, but be warned: failing to complete sections within the time limit will cost you continues.
