Very well done, and probably the best Shapes file of this whole site. I only give 4 stars though because the physics file glitches randomly and some secrets in certain maps like Waterloo Waterpark cannot be acquired with the physics file. The shapes file boosts the AR accuracy, as far as I know, and some minor other tweaks, noticeable in gameplay. And the sound file replaces absolutely nothing that I could notice. If you want a great physics file, get Aeon of Strife instead.
It's irritating how many Simplici7y mods completely suck. I'll plan to change that myself, but for now, this shit is getting out of hand.
Description is misleading, there's no "Feeling Doom" physics, which was what I was looking for.
A re-interpretation of the short story "Doom Repercussions of Evil". Done in the wrong place at the wrong time by the wrong person.
