Hey, I LIKED the Alien designs from the toys! Scorpion alien, gorilla alien, bull alien, panther alien, snake alien, rhino alien, killer crab alien, mantis alien, night cougar alien, wild boar alien, arachnid alien, and the queen facehugger.
A lot of those really looked nice and would be interesting to see.
Oh, and for the Xenoborgs, remember to aim for the power light on their head. Quickest way to kill them (although not as bad as the predator foot).
