I solved the problem in crude way:
added in gamemode_ config mp_teammates_are_enemies 1
It did not work from gg_ config file

Some CS:GO test results: my server: LGSM CSGO out-of-box Source-Python, last version. I used settings from ffa_deathmatch.cfg Problems i noticed: 1) after warmup, when round starts my client catches some lags 2) In ffa mode rewards work correctly while bots of the same team do not attack each other....

Greetings.
I noticed in sample you use "player.steamid" property, while in example of response you provided i see players { steamid: ... }

And thank you for your guide!

UPD: now i see my mistake.
