This level featured the little alien bugs on several occasions and boy, it's hard to kill that swarm unless you blow rifle or flamethrower; come to think of it but the Ripper also works well, The other enemy type is a monster that cannot be killed, you can only blow off it's limbs and apply stasis effect. Whoever designed the monster on the wall did a good job of making the game very difficult (IMHO).
