Should have been cheaper but worth the money if you don't have Opposing Force yet
-Excellent update towards the graphics area in Half Life, which has been lagging being in the recent years with the release of Quake 3, Unreal Tournament and Tribes 2.
-New Point of View in Half life which makes Half life, a trilogy now.
-Half Life inspired and original ideas for puzzles.
-Little too short in my taste. The story could have been easily expanded. It took me not much more than 5 hours to finish the entire game.
-Overly expensive, considering it's a) has only new single player additions b) no multiplayer mode of its own and nothing really new except for the new MP5/M4 model and the new High Definition Graphics Pack.
The Bottom Line
Overall a decent game to buy. Won't bring like over 50 hours of gameplay (or something like that) like Half Life did but it will bring you something to bring you back to the days of fustrations on how to solve this @&*(# puzzle.
