It may be worth mentioning that I created maps to allow two stage base / artefact missions using UFO:EU terrains within TFTD
. Made an Egyptian pyramid and everything. Doubt anyone ever found it...
The image luke just posted is a modification of the unused UFOs that were hidden away in UFO:EU's resources. I made some image data
so that they could be rendered properly-ish, but as I was only after the screenshots, I don't remember going all-out and making the tilesets actually playable. I doubt he'll have much trouble fixing that though.
