Summary: I have been playing this series since it came out...and I have to say that UT2004 added a whole new level to the Tournament. Single player continues to be fantastic and the multiplayer is more dynamic than ever with the addition of jumping wall dodges in UT2003. Onslaught is a wonderful addition that offers a nice alternative to small maps and gun vs. gun fighting. All-in-all, this game is amazing and will never die.
Summary: What makes this fun is how easily you can mod it. It is a showcase game for the Unreal engine, and as such, you can create your own skins and import them, change settings around to make things interesting (instagib, the one shot KO modified laser rifle mode.) Mind you the game has no plot at all and is repetitive, but its fun, and does what it is supposed to do.
