Vivendi has confirmed that they're going to add something to the PlayStation verion of F.E.A.R. that will not be included in the Xbox 360 version. 1UP reported today: "Of course, that could simply be tilt-functionality, but we'll have to wait and see."
Likelyhood will be tilt-funcionality or meta additions like more multiplayer maps. Details are slim at the moment, we'll have more soon.
For now, have a helping of in-game PS3 screens courtesy of Vivendi and Day 1. There are some cool lighting effects being shown off along with particle effects not to mention that the game is damn sharp coming off the PS3.
