Just managed to finish the game Aliens Colonial Marines. If you know of the Alien movie you would be familiar with it. This game also gives you the surprise when you get Corporal Hicks, the marine from the movie Aliens. He was supposed to be dead but if this is a confirm canon story, then he isn't really died. You will have him as a supporting character in your battles helping you. It is the ending that is frustrating. There is a "cliffhanger" feel to it as if there will be a sequel. Hope they get the sequel material out soon.
