Well it uses the Half-life graphics engine but it has a lot of bugs, the sound isn't good. It uses a lot of the computer. The graphis are of medium rate and as I've said before Oblivion is better, besides I don't think this game is able to face Oblivion in any manner. The graphics could be better, it could use less of the computer, it could not have too many bugs but were is the professionalism here?? I think that they should make a remake of this but with a lot of new things, no bugs, better graphics and shadows. The sound........One of the things that I like into this game is the "gravity" idea in the swinging of weapons and other action like running.
