#1 Chaos Island
Mapper: Circus BT
Description: Can you deal with the pain or are you a pathetic loser? We will find out on ChaosIsland!
Notice the pattern : most crappy mapmakers know their maps are crappy, and always challenge you in the description to sit though their creations. This is no exception, it's by far the crappiest map I've played in a long time. It's like the author took everything that could possibly ruin a VCTF map and threw them together into one cohesive disaster.

Texturing is a joke, here's a painful-looking repeating terrain.

Ion Tanks make their appearance.

Superweapons are scattered in abundance everywhere.

The background looks pathetic at best.

Low gravity is enabled for no good reason.

There's a mess of teleporters everywhere, good luck finding your opponent.

And worst of all, the entire map can be navigated underwater. You can grab the flag, and then swim all the way back to your own base without ever being seen. Common sense dictates this is not the brilliant idea the mapmaker originally envisioned. The plethora of teleporters only makes it worse.
This map does it all. If only it had random pits of lava or other unnecessary deadly traps, it could have been the greatest map of all time. As it stands, its lousyness was still enough to garner this year's grand prize.
For these sins and more, ChaosIsland is awarded the Gold Medal of Crappiness, and the 2005 Trophy!
