Protect all the VIP's with your sniper rifle.
Orbital Sniper is quite a unique game. You play as an orbital sniper and have a top down view of a large area.
The idea is very simple. You must protect any VIP that enters the area. The VI P's will be marked with blue and the enemies will be marked in red. Anyone else is an innocent civilian.
You use your mouse to zoom in towards the ground to get a better and clearer shot of your target. Once you have them in your sights, take the shot, then zoom out and wait for the next target.
I would say Orbital Sniper is a fairly decent game. It starts off a bit slow with only a few targets and then suddenly there are just too many. If your VIP gets killed or you kill too many civilians it's game over.
Orbital Sniper can get very boring after a couple of minutes and the graphics can be a bit blured at times.
