Here is the trailer for F.E.A.R. 3 explaining how the co-operative Contractions Mode works. You will need a good team for this as you scavenge all the weapons you can and keep an eye out for Alma as she roams the map unsuspectingly waiting to spring on someone she spots. F.E.A.R. 3 is out June 21st for the Xbox 360, Playstation 3 and PC.
