This Idea came to me while I was going through posts on the feedback section. You can notice a theme on visibility when people talk about the ship/indoor tile set. Door ways are obscured. Visibility is an issue. Etc. Then it hit me. What if I view it as intentional and what benefits does it give me?
Derelict Ship - Lights off. Emergency Lighting only. Imagine that tileset in the dark, minimal lighting. Only your torch/head lamp giving you the Emperors Light. Red flashing lights, green glow of Nurgle Funk. You could make your way to "engineering" to turn back on the power. It doesn't have to be pitch black. Just without white lighting. Heavy shadows. Could be fun.
