Awsome in almost everyway and highly recommended.
Technically, the game has very refreshing colors, the outdoor scenes are lit beautifully, while the indoor has a very shadowy and creepy atmosphere, I don't always seem to know where the Stroggs will pop out from. The game control is fairly easy and good. Quake 4 has a good of variety of enemies of different strength, power and technique which make the game the more challenging. The main character Matthew Kane has access to whole range of different guns ( Blaster, Machinegun, Shotgun, Nailgun, Grenade Launcher, Railgun, Rocket Launcher, Lightning Gun, Hyperblaster , Dark Matter Gun). The game texture is fantastic, and the whole environment is just superb. The audio and musical score is more than satisfying, it communicate with game action nicely. Storyline wise, I have to say that I couldn't find anything original or new in quake 4, it is good enough but it could have been better; but then again I guess it is an installment in a franchise.
I think Quake 4 is one of those games that will stay around for a little longer; it's addictive, refreshing and simply irresistible. I highly recommend this game for enthusiasts and entry game players alike.
