StarCraft 2's impossible mission has been beaten after 14 years by a guy who turned the 'Archon Toilet' into an 'Archon Bidet'

In Utter Darkness is a mission in StarCraft 2: Wings of Liberty that you're destined to lose. The protoss are making a last stand against zerg forces: The goal isn't victory, but to protect the construction of an archive that might aid some future species in their own war against the zerg. Hold the line, kill enough zerg, and you win—even though, y'know, you lose. But what if you could beat back destiny—what if you didn't lose?

YouTuber Davey Gunface set himself to the impossible task, and 14 years after StarCraft 2 launched, he's managed to pull it off. He didn't win, strictly speaking, because there is no win condition, but he didn't lose, either. By employing very high-level StarCraft 2 strategies, and taking advantage of some weaknesses in the enemy AI, he was able to lock the zerg into an effective stalemate.

Davey's breakdown of his strategy is the kind of deep magic that will make sense to committed StarCraft 2 veterans and absolutely no one else, but it turns on a few key points. The arrival of the final wave of protoss reinforcements includes Artanis, enabling what Davey calls the «Archon Bidet,» essentially a variation of the Archon Toilet, which I discovered today is actually a well-known protoss tactic that allows for large numbers of enemies to be wiped out very quickly.

«There's a reason I'm calling it the Achon Bidet, and not just the Archon Toilet,» Davey says. «Because here's the thing: Artanis has 500 energy compared to the base mothership's 200, so instead of being able to cast only two abilities at max energy, Chad-tanis over here can cast up to five in rapid succession.»

This is important because of another mothership ability, Mass Recall, which Davey was able to use to pack a few ground units into a specific small crevice. Not enough to make a real difference, except—he's going even deeper here—when combined with Vortex and Artanis' much greater energy cap, which enabled him to squeeze about 24 Templars into the space, which then morphed into
