I've played Vehicle Invasion on ONS-P3846. That's a cool map. I haven't played any of the others, though.
Most of my mapping endeavors ended when I realized I had no artistic talent to speak of. However, the latest attempt at creating something nice has produced DM-DesertTemple (name definently subject to change). I also have no idea where I'm going with it. First it was DM, then it was an Invasion map, and now I don't know. Probably just something huge that really doesn't do anything for any gametype.

This is just me screwing around with zones.
There is a secret passage way in here that leads to the screenshot afterwards.
