Is it posible to start game with only one agent w/o actuay picking second one ?

Yes, with the Lone Start mod. (https://steamcommunity.com/sharedfiles/filedetails/?id=605534148 ) Steam Workshop mods can be installed on non-Steam versions of the game using the Steam Workshop Downloader. ( http://steamworkshop.download/ )

Also, this game's community exists mainly on the Discord server ( url=https://discord.gg/dBUCcfcbdk ]https://discord.gg/dBUCcfcbdk[/url] ) so if you're interested in the game at all, I recommend to direct all questions there.
