One Punch - Borderlands 3 Farming Guides

Location: Lectra City on Promethea
Part of: Rare Spawn/Easter Egg
Drops: Sleeping Giant (Dahl SMG) and One Pump Chump (Jakobs Shotgun)

One Punch is a rare spawn/easter egg in Borderlands 3 which you can find in Lectra City on the planet Promethea. You'll find One Punch in the subway below Lectra City in the same area where you find Urist Mcenforcer. In order to fight One Punch you'll need to solve a rather straight forward lever puzzle which I go into detail about below.

As far as loot goes, Sleeping Giant (Dahl SMG) and One Pump Chump (Jakobs Shotgun) are both on One Punch's dedicated loot list. You can find the Sleeping Giant elsewhere in the game but the One Pump Chump is a drop unique to One Punch and can't be found (or is very difficult to find) elsewhere in the game.

One Punch Lever Order:
These directions are given assuming you are staring at the door/screens One Punch comes out of.

1. Furthest button on left
2. "wheel" lever on the right
3. Floor switch next to the wheel
4. On the same electrical box you pressed the button for the first part of this there will be a switch, flip it twice
