Very atmospheric .... makes you feel as though you are living the game.
Graphics - At the time this game was made these graphics were arguably the best ever.
Sound - Could have been better. The guns sound kind of weak, like BB guns. Also there is very little music in the game except at key moments. Other than that the sound is solid.
Value - Pretty average value here as far as first person shooter games go. 15-30 hours depending on if you play through as fast as you can or if you take your time and explore every little corner.
Tilt - This game was memorable and I enjoyed it a lot but I do feel that it is somewhat overrated.
