This was another video game-level-like build. I had to craft this entire facility rather quickly in Blender. These concepts are mostly just the blender model. I had little time for paint-over and I left the production before I had a chance to do any final backgrounds for this area. I used Fluent and geometry nodes to get the iced over and grungy look. Concepts are in order of appearance as Lara works her way through the facility.
