I worked more on my first Unreal map this weekend although it still is bland and needs loads more meshes. Here are some screens:
Upper Walkway:

Hallways:

Main Control Room:

This map is tentatively called DM-ControlRoom. It's a relatively small map set in this dungy looking basement loaded with machinery.
I've also got plans for 2 more maps I will build and release with my first 'Map Pack'. It will contain DM-ControlRoom, DM-Substation, and DM-ToxicRiver (all early titles).
DM-Substation
Set in an abandonded, war-torn cathedral/church that has recently become a human power station littered with machinery used to supply our cities with reserve power in a time of war. This will be my first map with outdoor environments.
DM-ToxicRiver
Toxic River takes place in a sewer system featuring catwalks, a trench filled with green liquid, and a green waterfall. This will be my first map using water.
I might start ToxicRiver tonight so I can break from CR for awhile (build the basic geometry for TR). I realized quickly making these maps I prefer the dark and dirty looks found more prominantly in Epic's Gears of War games although I will make sure to make some space and techy maps soon. I'm still getting used to the game assets (primarily the static meshes). More pics coming soon.
