STUFF:
Anyone wanting to be a judge, post in here. I need to know what games you can judge for (i.e. you have a copy of and know how to open a map in).
Posting screenies is fine, do as thou wilt.
Judges can map, but cannot judge their own map. Obviously since I'm the one running this thing I can't compete, but I'll be making one anyway.
PRIZE:
The pride of saying "I won the modDB HQ mapping competition!"
DEADLINE:
The all important deadline:
Thursday 21st August 2003
On the deadline please PM me a download link or email me the full map. I will then distribute them to the judges.
Results should be out by the 30th August, just in time for the HL2 SDK"
