This map reminded me of that one more for Half Life 2 called Gmod. All this seemed to me was a map to mess with F.E.A.R.'s physics blasting chairs around the map. It is a nice change of pace if you want to just mess around with a few friends or when your by yourself. Stack up a few proxy mines with some remote bombs and then blast them away with some rockets. Then sit back and watch your chairs fly over the buildings.
