Step 1
Jet Gun Parts
Water Valve — Flower Shop. By the spout across the street from Speed Cola.
Gauge — Bowling Alley. Go to the wall opposite the Mystery Box near the bowling lanes and punch the metal box on the wall so it breaks open. Interact with it to place the Water Valve, and hold your interact button until the meter is full. After the water pressure is full, the gauge will pop out and you can grab it from the ground.
Handbrake — Graveyard. Find the groundskeeper, Dennis Riffle, while waiting in the graveyard. Kill him and use the key he drops on the shed, then grab the handbrake from inside.
Wires — Radio House Electronics. Acquire a Mangler Cannon, either through shooting one off of a Mangler, crafting a Mangler Cannon scorestreak, or crafting a Mutant Injection scorestreak. You have to shoot through the door of the building across the street from Olly's Comics, then interact with the wire piles on the ground until you find the wires. You can also train a Mangler and have it use its own cannon to shoot through the door.
Crafting the Jet Gun
When you have all of the parts, find the crafting bench upstairs of the Motel. The door will appear closed, but when you get close enough to it, zombies will burst out of the door, opening it and revealing the workbench. Interact with the table to craft the Jet Gun, then interact again to pick it up.
Step 2
LTG Device
Interact with the SDG generator to spawn in the LTG parts.
LTG Part Locations
Part 1 — Inside the church, towards the balcony.
Part 2 — Jump to the roof of the white box truck and get it through the window below the zipline.
Part 3 — In the ceiling of Olly's Comics.
Collecting the Parts
Each LTG part is collected by using the Jet Gun's "suck" function to pull it in from a distance — you don't need to walk up and interact with it directly.
Crafting the LTG Device
On the roof of the bank, interact with the workbench to craft the device. Interact again to add it to your inventory.
Step 3
HVTs
There are two locations to place the LTG, both marked by an aether storm cloud: one at the church, and one by the bus in the street near spawn. Place the LTG at either location and defend it until an HVT spawns.
When the HVT spawns, it will either be an Abomination or a Mangler. Both need to be killed inside of a Dark Aether Field Generator trap, with an aether canister inside that same trap.
First Canister
The first canister can be retrieved inside of the church, and must be carried and dropped inside the trap location. When the HVT is killed, its essence transfers to the canister — carry it back to the SDG inside the church. You are timed during this step; not completing it in time will force you to flip the round and defeat another HVT.
Second Canister — Strauss Counter
To get the second canister, pick up the Strauss Counter (which will replace your tactical inventory slot), and calibrate three projectors around the map:
- Bowling Alley Lawn
- Backyard of Groundskeeper House
- Yummy Freeze Roof
How It Works
Each Strauss Counter shows a color and a level. The projector must be calibrated to the opposite reading — when the counter shows Green / Low, set the projector to Red / High; when it shows Yellow / Medium, set the projector to Yellow / Medium; when it shows Red / High, set the projector to Green / Low.
When all 3 projectors are set to the correct frequency, this will unlock the second canister in the spawn area. Use this to complete the second LTG/HVT encounter, then bring that filled canister to the church.
Final Step
Final Encounter
With both canisters filled and placed in the STG, interact with the STG to start the final encounter.
