UnrealTournament, the game that has been around for almost a decade and seems to be indestructible is still one of the more popular ones.
Not just because it is probably the only game still able to pass the 600 comments count on ClanBase for a single match (EC iCTF Final).

One of its younger gametypes, BunnyTrack is another reason for UT's retaining activity. The addictive mod is often described (besides nerve killer and concentration trainer) as UnrealTournament's equivalent to Defrag, which is not quite accurate though, as there are some major differences. It however, discloses BT's main focus.

The 1on1 BT WorldCup is organized by BT-MaTcH and known for its coverage quality and the world wide online matches. Former cups featured online games like those of players from Portugal Portugal vs from Australia Australia, New Zealand New Zealand vs United States of America USA or Canada Canada vs Poland Poland. The cup will again be hosted on ClanBase as their own website is still under constrution this however, has rather been an advantage in the past, because the crew had more time to concentrate on coverage. Shown for instance by the pervious season's 216 reports per cup, an amount that is unique on ClanBase as well.

Despite of the high skill level reached in the cup, it is open for all players. Besides the main, first league there will again be at least 2 other leagues for those who aren't too advanced yet or just want to give it a try. The maps of the lower divisions are held easy.

Sign ups are open. Players who are familiar with ClanBase and 1on1 can sign up here (note that you have to switch to your 1on1 personality). Others can find a description of how to sign up here.
