Amazing and it's only a demo!

I just finished this game and all I have to say is wow! The game play is smooth and action packed and the sounds and graphics are unique and fit in. The idea of only being able to respawn if you still have teammates left or you have to start the level over is fun and I found that I was looking out for my teammates a little more than just running through. Even though this was only a demo I'd still give this a good rating even if this was the full version, it even manages to incorporate something of a story. But because it's a demo it's short and a little buggy, but that's expected. The main thing that I suggest that you add in the full version is a little variety, it would be great to have more than one gun, to be able to use turrets and throw grenades. Keep up the good work!
