Got this as part of the EA Origin Humble Bundle. This seems *exactly* the same as the Xbox 360 version.
2887 Played the prologue and a bit of Chapter 1 on Impossible difficulty, which is indeed possible ... for now. Plays fine on my work computer with an Xbox 360 controller.
2940 Played chapters 1-5 on Impossible difficulty in co-op with Jauert. The game works pretty well in co-op - you wouldn't know this was originally a single-player franchise. It's hard on Impossible, but it is ... possible.
