After a few days of fumbling around, it was decided to change the rules of the game or call it quits. In some circles, this disqualified Twitch Plays Dark Souls from being a legitimate playthrough; it subverted the way Dark Souls plays. They essentially changed it from a 3D action game into a turn-based affair.
Was it cheating? Sure. Was it the only way for Twitch Plays Dark Souls to move forward? Probably. Does that mean their achievements are meaningless? No.
Soon enough, they beat the Asylum Demon.
A little later, they beat the game's hardest boss, Orstein and Smough. With O&S slaughtered, it seemed a matter of time until they'd actually beat the game.
That time, as it turned out, was on Saturday. 43 days, eight hours, 14 minutes, and 23 seconds after attempting the nearly impossible, Twitch Plays Dark Souls was able to finally say they'd beaten Dark Souls. They only died 904 times, too!
Naturally, they are already on Dark Souls 2 and it's just as interminable to watch.
