Something I made a few years back for a school project. In terms of content I massively undershot my original aims, but visually it came out better than I had expected, so there is that.
Originally the plan was to create a half-hour mod, featuring 2 custom NPCs, two weapons and various other props, with voice acting and a strong sense of story. In the end I had two severely truncated maps, but functional and visually and aurally striking (imho).
Enjoy?
