Isis

The custom textures are fantastic. If you're a mapper seeking a change of pace from the usual Scythe 2 Egypt, both ISIS.wad and Osiris.wad, which provided some resources, permit use of their assets. (Although they would need cleanup to gel with the most polished of modern styles.)

By modern standards, ISIS.wad hasn't held up, either the name or the gameplay. Outside of a few moments, it stays at a difficulty that makes the early parts of Doom 2 feel like a TimeOfDeath map. The bigger issue is that it is also huge and confusing, with progression being lightly marked at best. Near the end, I unwittingly teleported to the start, and I had to reload a save to avoid minutes of backtracking. All the monsters are stock, so if forced to replay it, I'd either use -fast or throw on a gameplay mod that buffs monsters. The saving grace is that the textures make the outdoors and caves look pretty.

The text file suggests using Doom Legacy, but few people in 2020 know what that is. Fortunately, the wad ran perfectly for me in GZDoom. It requires jumping and swimming.

Bumped up a star for the cool assets, especially since many were crafted by the author.
