I really like the feel and look of this game. I also really like how the wide variety of weapons with different strengths, and the upgrade/ability things allow you to sort of make your own class to fit your playstyle. I think this game would also be great if it had online co-op, or maybe LAN so you can play with your friends. Also maybe a bit of a story, like a background on the character, maybe about the enemies and who/what they are. Such a great game though. :)
