Summary: When I first played this game I felt it was a Halo rip-off. After finishing the weak campaign I still felt like it was a Halo rip-off, right down to the scope. but that doesn't mean it was bad. As I said the campaign is somewhat weak and didn't give me much. it lasted about 6 hours and ended with a boss battle that was at first cool but then changed to annoying, as it involved an over-powered villain surrounded by infinitley respawning soldiers.
