Chill / Kill / Upgrade
This code is over 6 months old. The code may have expired and might no longer function.
Hold "Interact" (F) for friendly mode! Hold "Reload" (R) for upgrades! Work in progress.
Note: it should work with any map in the team deathmatch category, even the "repurposed" control or assault maps, but I was way too lazy to figure out which maps overlap in the workshop.codes settings.
