I found this to be a good game. I'm not really a fan of these shooting games. Well, some are great but that's mostly because you have more mobility. I thought the music was good and fast-paced. There seemed to be a lot going on. I liked how you didn't have to click seperate buttons to hide and reload.
It went together nicely. I like the design and even if it's not that creative, it still works well. It's basically a good old standard shootup. If you like any of those kinds of games, you should enjoy this. I am and I obviously enjoyed it.
