Super Mario 64: The Underworld v1.1.2

HOLY SHIT(ilizer)

Okay, THIS WAS AWESOME, but man...that final boss...damn he was hard...
Cool, but so...damn...hard. must be skill issue because I haven't played sm64 in a while...but hey, y'all did well making this! and the theme for the boss... chef's, kiss.

THE BEST ROM-HACK EVER!! I LOVE IT!!

The concept is very well executed. It feels like a direct Mario64 dlc content.

Perfect hack made in coop, it changes everything and that is what gives it the essence besides having a good story and the level is quite wide to explore, incredible animations, the battle against shitilizer is the best because it is complicated but possible, definitely beautiful hack

Underworld is a very impressive mod by Agent X with an interesting story, a cool custom boss fight, a cool custom dialogue system, wonderful visuals and a boss theme composed by Trashcam that slaps. In terms of difficulty, collecting the stars isn't hard, but the boss fight can be real difficult, especially to solo players.

The Shitilizer was a fun boss to fight, learning how to defeat him alone is a great experience. Short and sweet, and an excellent time with friends! :]

A incredible rom-hack, wich deserved the prize it won. From the premise and/or story to the final fight, a solid experience all the way. A hack EVERYONE must try at least once.

An excellent modification that changes the game so much it's almost unrecognizable. This mod truly pushes the limits on what can be done in the PC Port Decomp.
