We already knew it was coming, but Vivendi finally let us know that they know that we know and officially confirmed Monolith's spooky FPS. The port was originally anticipated due to developer Monolith's other creepy FPS, the Xbox 360's Condemned: Criminal Origins, having a similar code base to F.E.A.R. When Condemned was ported to PCs, the logical assumption was that F.E.A.R. could be ported to the 360.
The port is being handled by "Chicago-based Day 1 Studios, who worked on both MechAssault and MechAssault 2: Lone Wolf" and is due out this fall and will be on display at E3 next week. We'll let you know if the graphically demanding title appears to be making the transition smoothly.
