Managed to get a copy of Universe Soldiers a few days back, and I already completed it today. Great game, although a bit easy. I finished the game on the easy mode in little time, and started going back through playing on the hard mode. Only difference between the two modes is that on the hard mode, the ship/car goes much faster, making it harder to control. Made it about a 5th of the way through on the hard mode, but decided to take a break, as I was getting bored by that point.
Great game though, well recommended. Definitely has Pac Man as its inspiration, but to be honest, I prefer this to Pac Man due to the special items and things like that.
