Here are some screenshots of my mini-episode-in-progress.
The left one is a map called Federal Hill, using the ik2k texture set. It’s going to be a Lovecraftian New England town invaded by grunts. On the right is part of an experiment with the speedbase textures. It’ll be the second of a pair of base maps; the idea is you start in the modern idbase half and cross over to this rusty gothic seedbase part.
