You can really spend a lot of time on this one and not even notice. You need to plan your nex move carefully and re-load your game a lot of times to get it right.
Great game, a little unfair sometimes, you are literally next to an enemy with a 99% hit chance and you miss. But putting aside all the frustration you can have lots of fun with this game.
I've been playing this game since its release back in the 90's and I never get tired of it. I've played both the classic and enhanced versions, and they're just great, the Quake series is in the top ten for me in the genre.
