The "Iron Man Run" in Super Meat Boy (available at Steam) is completing a whole chapter (Light World recent patch added achievements for the Dark Worlds, too, normally 20 levels, except the last one, where there are 5 when the information I've read are correct) without one single death allowed - which gets pretty intense in later chapters.

Iron Man Run - Light World:
Iron Man Run - Dark World:
Boss fights with Outros:
In my opinion this was was even harder than the "The Kid" Warp Zone, especially because you only have 3 tries on every of the three stages. You might disagree with me here, but hey - I REALLY hated these three!
