When you get to the end of chapter 2 there are 5 supervisors guarding the entrance. You need to get the attention of (preferably) every bot and for that I reccomend placing the teleporter near the table next to the far right supervisor, then standing on the left of the far left supervisor. if you manage to do this without getting noticed look through the teleport view to get the far right bot's attention. You could also just stand next to the far left robot if you want.

After getting the attention of the bots, it's just the matter of staying alive (you might consider turning on smooth locomotion if you don't have it on already).
you can do this in 2 ways:
the first one is the chad way, where you keep dodging bullets until someone dies.
the second is the ♥♥♥♥♥ approach, where you back out when one of the bots get hit and wait till they bleed out.

If you want more fun out of the situation, try mutators! But watch out because most of them turn off achivs so get it done before trying them. the screenshot below was made with zero-g

I hope the guide helped, I tried to explain everything as clear as I can but if you don't understand something let me know.
