Okuplok. 23 thousand enemies in a sequence of extremely challenging fights. Created in 2012, this massive slaughtermap for classic doom was long thought to be impossible. And yet, as time passed, and as new strategies and tricks were discovered, the possibility of a non-TAS UV Max speedrun of Okuplok became closer and closer to a reality.

You are watching the longest standing doom marathon that has remained unconquered for 13 years. This is a 6 hour long grind with the goal of reaching the exit will all monsters killed, and without dying once. And by the way, there are no save games, and no checkpoints. The smallest mistake means you go all the way back to the start.
