Better campaign than online
Not to everbodys taste, but i grew up watching the films and to play the role of a predator or alien is awesome.
The Alien campaing is very good and i really enjoyed it.
The predator campaign started off pretty hard but once you get into is very good and using his arsenal of weapons and visons is top notch.
The Marine campaign has got to be the scaryest coz its quite dark and to hear your motion sensor beeping just reminds me of the films, and not knowing waht it is is pretty freaky.
Online play is ok worth ago but you do have to play for a while and get used to it because i just get wasted!
