Gee, I wish Tripwire had a mapping contest that would result in making the best of the submitted maps official!
No offence but TWI is too slow with providing maps, mapping contest or not. Why dont you yourself have more people working on maps? They came out way faster with RO1. If you are not able to speed things op this will just remain a niche 1000 player game. Maps are essential right now since the maps that game with the game are not focussed on optimal gameplay.
