That jam sounds rad but idk if any of us heard of it before? We just rly wanted to make a resident evil game lol (one of the cut things was a mr x style boss you could spawn after a set timer)
For the actual style we found a shader on the asset store and slapped that (and much volumetric fog) onto some existing low poly assets. Other things may have been done too - Tam might be able to go into detail cause he mainly handled the look and vibe??
