The custom DODS maps definitely give me an appreciation of the steps mappers have to take to make a great map.
Layout, textures, playability, frame rates, spawn protection and making them all work together is the goal.
Here are four new maps to try out. They aren't polished but are a break from the stock four.

dod_alterna and dod_lerouge are both small maps that provide some intense fire fights.
dod_battlecreek is inspired by Halo2. Small and frantic with a two man cap in the middle.
dod_snow_battlefield_final is one HUGE map. The mapper has added sandbags and hedghogs to provide cover but its still an rifleman's map.
