Open source version of a development tool, called wxConsole, used with the Diesel game engine (PAYDAY: The Heist, PAYDAY 2, RAID: World War II)
Currently only works with Lead and Gold - Gangs of the Wild West, as that is the only Diesel engine game to be released with the ability to connect to wxConsole.
I am not affiliated with Grin, Fatshark, Starbreeze Studios or Lion game Lion.
