...is a pile of shit! If you liked the original then this is worse its just a contradictive unfinished piece of confusing waste of time, its not an expansion its meant to be a new game, its strange i was looking forward to it and its so disappointing, please don't buy it!
This game is going to ruin what stalker was.

ANd stalker wasn't exactly the best game in the world either. Awesome concept, nice graphics, tons of quests, but firstly: There were hordes of enemies, in a negative way. They flooded the entire game. Secondly, the engine was severely flawed. You couldn't run it on any computer without lag. But I give them cred for the absolutely awesome concept of a post-fallout Chernobyl to roam and rampage in.
