The first expansion wasn't to bad. The first expansion actually looks a bit like this true sequel to be honest. Both seem to take place after the events of the original game when Alma escapes the facility. Basically your playing after the huge explosion which takes place at the end of the first one.
It is a shame to see though that this game looks just like another FEAR. It was speculated this game would have the player running through the blown up city, but all the in-game video thus far is more indoor combat. Which aint bad - But i've allready played three FEAR games that have the same combat and scares. This game doesn't look any different. I'm sorry, but it really doesnt.
