Every step in order, no explanations. Open the full manual when a step needs detail.
Turn on the power
! Everything on this map is gated behind the power. It brings the perk machines online and activates the teleporters.
Link the three teleporters
! The Mainframe door opens a little further with each link. All three and Pack-a-Punch is yours for the rest of the game.
Pack-a-Punch
Free power-ups from teleporting
Free 100 points at every perk machine
What you get
! That Gateworm icon is the thing that matters long term — The Giant counts toward the A Better Tomorrow super Easter egg, so it has to be done if you are chasing the full set.
Prerequisites
! Pistols and shotguns will not reach the first target. Upgrade something you can actually aim with.
Shoot the control panel
Shoot the three toys
! Guides disagree on the exact objects: some describe a teddy bear in a cage near Z-A, a bear inside a water canister at Z-B, and something shiny on the balconies by the power switch. The three areas are consistent across every source, so search those and shoot whatever toy you find.
Claim the Annihilator
! In co-op every player has to interact with the furnace to get their own reward. Do not walk away once you have yours.
