These commands will activate the boss teleport sequence, just like if you activated it from a transmitter.
USING THESE COMMANDS WHILE OTHER PLAYERS ARE IN THE ARENA WILL KILL THEM AND THEIR TAMES.

The Overseer will show up white regardless of difficulty you choose the only way to fix that is opening the Tek Cave door legit or you spawn the tributes into your inventory and turning on GCM and pressing E (PC) or A (Xbox) or X (PS4) on the tributes to activate them to spawn the tributes use:
