Now this was a tough one for me to review. The game is indeed very challenging, not to say difficult. I remember a few moments at the beginning when I was utterly frustrated, and convinced that some levels are impossible to pass. And then I passed them, to my great satisfaction. On one hand I agree with some of the previous reviews, that you cant just go around criticizing a game because you suck at it, but on the other hand a game should be fun to play first of all. Some of the best games around follow the motto 'easy to learn, difficult to master', and to be honest, I think this time the bar was raised a bit too high during the 'learn' stage resulting in my score of 9 out of 10.
The graphics and weapons have a great look and feel, but that's not so hard to notice is it? (my presonal fave is the GD-ACG6, it reminds me of the magnum in Half Life 2)
Oh, one more thing, the weapons could use even the shortest descriptions (like the matador, it took me some time to figure out that you can charge it for a more powerfull shot)
Anyway, great game, keep up the good work!
