Extremely cool and fun! Make sure to get the 1.0.1 version though, the 1.0 release on ModDb is missing the essential PK3 file and so won’t load.

The spritework is incredible and I love the 4-armed archvile, the dual-wielding chaingunners, and the revenants, which now fire both their rockets at once! The updated spider master mind and icon of sin are really great too. There’s some twists that make those boss fights new and interesting too, but no spoilers from me!

My biggest complaint is that the texture work is dull. Not sure how much of this is because of the base Doom 64 textures, but I remember D64 having a lot of blues and purples (more so than on original doom). This mod though is 100% Quake-certified Brown. Even stuff that was colorful, like the green marble pillars in Babel or the red intestinal textures in Hell, those are brown now. Worse, they added colored lights into several sectors (nice) but used a grey color for so many of them so big chunks of many levels, that aren’t brown, are desaturated grey. It’s extremely boring and considering how well done everything else is, I really don’t understand this choice.
