User Rating: 9.6 | Unreal Tournament 2004 (DVD Version) PC
Unreal Tournament has been around since 1999 and now the 3rd in the series, 2004, has arrived. I have played the original and the best memories for me are, the headshots, flak cannon, Redeemer, the GODLIKE bots and of course innovative gameplay. UT2004 lives up to this reputation bringing back gametypes such as assault but the one gametype most people are intredted in is ONSLAUGHT. the general idea is that each team has a base, construct connecting nodes and then u can destroy the base. Although it is a lot more complicated than that, it is easy to start playing. Also this is the first UT to have vehicles which is just what the series needed. Over all UT2004 is a great game. The only problems are that new players could find it difficult against more experianced people online.
But there is one more thing, the customisability of this game is HUGE. The unreal editor 3 is very easy to use and the amount of mods on the market would fill up Bill Gates Computer easily (by the way if u stuff Bills 88 million under his bed, it would take him 18 minutes to hit the floor but include intrest and he will never hit the floor). i would recommend Chaos UT, and the Community bonus packs are great too.
