One of the best.
The multiplayer game is basicly the same as the single player. Even if noone else is around you can host games with computer controlled opponents . The game comes with a match making system built in so you dont need other programs to find servers. There are some cheaters online but most of the time you can find a game without them.
The weapons are better than ever and UT has some of the coolest weapons that are fun to use. Also if your playing onslaught there are vehcials and they each handle diffrent and every one of them are really fun to use. This game will also run on older PC's because you can turn the graphics options way down if you want.
