Special thanks goes to me for reminding him about this 

Definitely not the worst halfhack ever though. I've seen far worse. The atmosphere of Brinstar is particularly unique and there's some interesting tile design in places.

This was a half-assed half-hack I think I was working on about two years ago. I literally knew next to nothing about level design, appropriate challenge, creativity... man. "lol waturs fun guyz rite? lol flowing water"

I should mention Aegis has two brief pre-gravity underwater sequences: one is about four rooms long in the sewers and is over fairly quickly, the other is later in the game and is just a room or two of underwater grappling. Nothing like this... sad excuse for a hack. :P
