These are new versions of maps considered classics, mostly from CS:GO, and CS:S, to CS:2 (Source 2 Version of CS:GO). I reviewed the textures and models of every map, ensuring my ports were authentic to the original by replacing them with the closest alternatives. I borrowed some textures from ambientCG, Polyhaven, or from fan-made remakes of older maps like potatoman44's Piranesi remake, if there weren't any alternatives.
