Probably the best 3PS I've played next to Freedom Fighters. The gameplay's just addictive fun and works really well. Good score, excellent voice acting. Good variety of weapons to suit your playstyle, and you will will feel like a god and saviour of the world at the end.
I'm a little surprised it didn't review better… It suffers from some minor technical glitches and a few instability problems, but the frequent check point system means that's just not really an issue. This is on my “must play” list, and I'm thirsting for the next two in the trilogy.
For $30, you'd be a monkey to not buy this. If you want a cinematic storyline with solid third person shooter gameplay, then get this now. You won't be dissapointed.
