Check out the main character in action in this 1st video, and you even get to see him jumping from wall to wall in zero gravity. They explain in the second video that you cant just shoot these monsters dead, you have to take them apart piece by piece. If you shoot out the legs, they crawl at you, shoot one arm out, guess what, still one more arm to rip you open with. You have to take them down and make sure they stay that way. Also, if you have been following the animated comic, you can see the 3rd episode in the 3rd video posted below.
