(Copying Kasperg, and using this thead as a WIP portfolio. :))
Here's my latest attempt an HLDM map, based on the Enterprise-A from Star Trek.
Battle areas will be on the inside and the outside of the ship. There will be various ways around the ship, including Transporters, Jeffries tubes, Airlocks, Turbolifts, and maybe even a shuttlecraft!
I realize this is not the most feasible/conventional way to build a multiplayer map, but I think I'll be able to make it work.
Some Alpha screens:
Hallway:
Torpedo bay:
Shuttlebay:
Bridge:
Exteriors:
Hammer Screens lol:
