G-Loc: Air Battle

G-Loc on the Master System is quite different to the other ports. You can choose mission type awarding a varied number of points, with a chance of bonus missions appearing where you can gain more time and missiles. If the game is not going your way, you can spend your points on extra time and missiles.

I play on Ace difficulty which requires quite a high point count to end the game but the game can and does end sooner than that. There is a second boss/base ship to attack but it did not give me the opportunity to show it. There are ranks to climb through which offer higher point missions. I think (but not sure) I hit max rank by the time the Final boss plane is destroyed.
