I thought I should say something, but then I've changed my mind.

good

sheva.av?

I started a ZKDOTA test game long ago, but it was broken and I haven't given it a go since. It was the latest version if I recall correctly. No one has fixed the game mode as far as I know. To attempt to play the latest version, you should type "!game" in a room followed by the right identifier. This map is also needed apparently.

I don't know which identifier is correct. It could be "zkdota" for example. As far as I know, the mutator will be downloaded via a thing called "rapid" that contains various games supposedly.

Maybe Spring Files is hosting the mutator.

Tried to start it with spring.exe, doesn't work :(

It requires some kind of depended archive :(

So it detects the game version " !game dota 1.2.6.18 " after I download it manually and placed into the "D:\Zero-K\steamapps\common\Zero-K\games". But when I start the game with lobby it requires some kind of dependency file.

Here is the snip before pressing start:

Here is the image when I pressed start:

So it's clear it requires "zero-k-v1.2.6.18.sdz" that I downloaded it from here: https://api.springfiles.com/?springname=Zero-K+v1.2.6.18&filename=&tag=&sdp=&category=game
I have pasted now that file into this location: D:\Zero-K\steamapps\common\Zero-K\games and this is what happens when I start the game:

So it works but it seems to be broken.
