Tech TV's X-Play reviewed Unreal Tournament 2004 giving it a 5/5.
The writer also comments on the VOIP feature:Now that "Unreal Tournament 2004" has arrived, "X-Play" would like to go on record as saying that this is the last competitive multiplayer shooter you'll need -- ever.
Too bad we all get painted with that brush.This welcome addition improves communication. But it also highlights the worst part of UT. Most players are idiots, jerks, or both. The anonymity of the Internet brings out the worst in some people. So if you choose to leave voice chat on, be prepared to endure sophomoric ramblings from players in love with the sound of their own voice. But that's a minor nit directed at the childish "Unreal" community, not at the game.
