Haha, that's it! Thank you so much! In hindsight it looks something meh to replay, but I'm feeling the need to play something nostalgic after finally finishing Ancient Aliens.

I'm looking for a pretty old WAD where each level is a different website, and there was a big enemy with a soulsphere head that spammed the SSG sound, some of the levels were duds and instantly were skipped, and the final level had like a lava floor with IoS cubes summoned everywhere?
