There is a lot that is great about this game but also a lot that is wrong with it.
While i played i encountered quite a few bug like the player getting stuck moving and firing in one direction and in fact the biggest reason I would die was because when I really needed to I couldn't turn around.
Another problem I had was as I was playing I would accidentally hit a button that would cause the fullscreen to close and i could not get it back to full screen again without closing and starting over.
Now in the last boss fight I encountered a glitch that killed me twice and almost took my last life.
As I was fighting I got hit when I backed off and out of range I kept taking damage even though the thing was missing.
The pistol right off the bat was useless as if you ran out of ammo on you assault rifle The things would kill you before you manege to kill even the small ones with it.
One of my biggest concerns is that you just don't do enough damage to them.
Anyways Out side of that It was a fantastic game and in spite of it's flaws I really enjoyed it.
