What just happened? After more than a decade of punishing attempts, one of Doom’s most infamous community maps has finally been conquered under the most brutal conditions. Classic FPS streamer Coincident completed the “Okuplok Slaughter Map” on Ultra-Violence difficulty earlier this week, eliminating all 23,211 demons in a single, uninterrupted run with no deaths and no saves. The entire run took just over six hours.

For the uninitiated, the map was created over 12 years ago by the reclusive Doomworld user Okuplok, and it’s infamous among Doom veterans. It’s essentially a grueling gauntlet of relentless enemy waves, often packed into tight corridors or sprawling arenas where the slightest mistake can mean instant death. Its reputation isn’t just about size – it’s about how brutally and unpredictably it punishes the player at every turn.

Before Coincident’s run, people had beaten the level in pieces using save states or tool-assisted speedruns. Those are impressive in their own right, but this kind of single-segment, full-clear run at UV-Max difficulty had never been done by a human.

Coincident wasn’t new to the challenge. In 2023, he completed the same map on the easiest difficulty setting, where players take half damage and receive double the ammo. Even that feat required massive planning and flawless execution. Ultra Violence, by comparison, demanded far more from both the player and their strategy.

In the lead-up to this latest run, Coincident released a series of YouTube videos breaking down the map section by section. He explained how to navigate each encounter, where to find small advantages, and how to manage health and ammo without taking unnecessary risks. Still, despite all the preparation, Doom’s randomized damage values meant he also needed a bit of luck to survive the later arenas.

The full six-hour stream isn’t action-packed from start to finish. Much of it involves kiting enemies, baiting infighting to conserve ammo, and slowly chipping away at massive hordes of demons. But the tension spikes during key moments, especially toward the end when Coincident’s voice tightens and his breathing grows noticeably heavier.

When the final wave fell, the relief was instant. “Okuplok is done! Done, done, done, done, done! Oh my god, what a ride,” he exclaimed. After thirteen years of players trying and failing, it finally is.
