I finally managed to solo this map by myself on ultra difficulty. I've previously made a video where I tried to do the same on the 2P variant (same map) with Leshrac. In that video I got pretty close but couldn't finish it off.

The name of the custom is in the workshop is "Dota 2 Horde Mode *UPDATED*"

Notes:
1. I have cheats enabled because my intention was to experiment with different item builds, but then I felt like giving it a real attempt. Cheats were not used.
2. I got lucky that I didn't have to face the Leshrac boss. I was preparing for it with the mage slayer, but not sure if I would have beaten him
3. I should have gotten desolater 3 instead of daedalus for more damage
4. This is my first try on the 3P map. Usually I use the 2P map. Not sure what the difference is, the map seems to be the same but I think more creeps spawn on this map which lead me to get more gold with Alchemist. This was important for me winning I think.
