OliveD has just announced his project Fortune's Run over at ZDoom, mostly looking for some people to help with the development. It is intended to play in the vanilla resolution and the author  tried to make it 90s styled, though closer to the Build engine games than Doom, really. The original concept was themed after Dark Forces. You play as a famous alien thief out on the hunt for a map leading to a highly valuable artifact. You'll be sneaking around on ships, shooting your way through cyberpunk-ey cities and there is even a jungle level in the works. You can find further information in the dev-thread over at ZDoom. Support her, give her a hand, the project looks very promising!
