Doom II: Dark Tartarus - Map 40 - Horrible Things - UV-MAX in 45:03

At the timestamp 44:07 I killed all monsters present in the map from the start, all resurrected monsters and all spawned lost souls before Icon of Sin spawned first extra monster. At the start there were only 690 monsters, but I ended up with total of 1856. By using presented route and also by setting flag "Icon's death kills its spawns" (sv_killbossmonst) to true, we can see 100% at the end of this map.
