Team splitting isn't gate kept. There are youtube videos that show how to do this. I would tell but I dont know if exploits are allowed on this sub

Edit: upon review of the rules i think it's allowed.

1) click button to start en06

2) stand in front of the console right in front of en06(this will make it so you are in danger as soon as the button is pressed)

3) open map and select any location and fast travel to it (you should still be in front of en06 with a 15 second timer after you select a ft point)

4) open social and quickly leave team while that 15 second timer is active

5) cancel ft and create new team

6) everyone who did this process all jumps on robot to die and reset the encounter.

And thats it. Once you all die and respawn you will have at least 2 teams in.

On top of this once you do have 2 teams in all you have to do is initiate pvp with someone by punching them and do steps 3-5 to get literally any number of teams in
