An early 20th-century apartment building corrupted by a horrid flesh. On its roof is a small train station, with a creeping descent into its lower floors.
I made a point early on to not include any interior windows inside the buildings in the project, and intentionally misalign floors with the windows visible on building exteriors to add to a sense of confusion and give the impression of non-euclidean layout.
This area was part of a larger personal project built and lit with Call of Duty: Black Ops 3's Mod Tools using in-engine BSP modelling and existing assets from COD: Black Ops 3, COD: WW2 and Bioshock 2.
