Alright, this one may be just for me and those who have ever played World of Warcraft, but this video is pretty damn mindblowing.
Some dude killed one of the toughest raid bosses (Yogg-Saron, the tentacled, thousand moutheyes Old God) from the last World of Warcraft expansion by himself. This encounter used to take either 10 or 25 HIGHLY coordinated people and was the final boss of the game for a bit. I remembered doing this with a ten person group and still wiping for hours.
The real life equivalent would maybe be like an NBA player playing 1 on 5 vs, say, a high-school team. Yes, he’s a lot more skilled than the high-schoolers, but it’s still a cooperative team-game at heart.
Apparently it took him hours of trial and error to get the strategy and execution done right, but, by golly, he won in the end! I tip my hat to you, sir.
