Im 19, i go to college for my bachelors degree in mechanical engineering, and in my spare time i surf Levels4You.com, make maps for UT2k4 or RF, model stuff in 3Ds max or other mod related things. When i comes to modding i don't really have a specific trade though i just kinda learn it as i go. I worked with RedFrog on a mod called MarsWars for a while but quit about a year later, even though he did most the work :o).
This is a map made by evilmrfrank which features a Mars base built into a cliff.
