Super Mega-Metroid X-2
Release date: November 12th, 2013
This is a linear hack that highly requires save-state abuse and pretty much all skills. You have 1 hp through-out the entire game, and it's a spike-fest. If that wasn't sadistic enough, you can't die, ever. The game has a glitch where you get stuck in the ship and need to reload the rom. This was only made for TASers, but other regular players liked it, so if it's your cup-of-tea, have at it.
Also, I should note that most areas have two paths. Technically, you'd have to beat this twice to experience the full-game.
