My first DooM project after over 12 years is going to be a mini-episode with 6 maps. Simple story: All water on Earth is contaminated and very unhealthy. Fight the demons, find the source of the contamination and beat the boss. I don't have a good name for the project yet. The working title is 'Acid Wars'.
As of today, 3 maps are almost done, one more is currently in work, the rest only exist on paper. Here are a few screenshots:
