Jump to a section!
Power on the Telescope
| 1 | Repair the Harmonic Oculus |
|---|---|
 Reach the Observatory Dome and Interact with the Harmonic Oculus to start the repair objective. |
|
| 2 | Find Two Harmonic Components |
 Search the Luminarium and Machina Astralis for the missing harmonic components. Both pieces will be found beside a dead zombie. Their spawn locations each match will be random. Tip: You can actually already pick up them while on the way to turning on the power. |
|
| 3 | Defend the Harmonic Oculus |
 Return to the Observatory Dome and install the Harmonic Components. After placing them, activate the power and defend the Harmonic Oculus as it restores energy. Once the sequence completes, the Pack-a-Punch will be unlocked. |
Collect 4 Contraptions for the Wonder Weapon
After restoring the power, you need to get Contraptions to activate traps and kill Oscar. These can be done in any order.
| 1 | Find Oscar |
|---|---|
 Oscar will spawn at a random location on the map. You can easily track it by checking your map and looking for the Elite Enemy icon:  |
|
| 2 | Destroy and Collect the Damaged Drone |
 Once Oscar sees you or once you shoot it, it will summon a protective drone. Focus your fire on the drone and destroy it to collect the Damaged Drone quest item. |
|
| 3 | Get Car Battery from Ol' Tessie |
 You can get the Car Battery from Ol' Tessie once you Pack-A-Punch a weapon and shoot inside the car. The car battery pops out of the hood. With the Car Battery and Damaged Drone, you can activate the trap in the Luminarium. |
|
| 4 | Obtain 3 Absolute Zero Fragments |
 You need to get 3 Absolute Zero Fragments for the Rocket Ship's trap next. To harvest the fragments, you need to shoot the purple crystals that spawn on the map with Cryo Freeze on your weapon. You can get Cryo Freeze via Arsenal Machines for 500 Salvage. You can find tons of purple crystals at the Stargazer's Courtyard located in the middle of the map. |
|
| 5 | Get the Aberrant Wiring |
The last Contraption to get is the Aberrant Wiring. You need to look for a blinking lamp outside the buildings and shoot it to drop the wire. |
Kill Oscar with Museum Infinitum Trap (Rocket Ship)
| 1 | Lure Oscar to the Museum Infinitum |
|---|---|
 First thing to do is to lure Oscar to the Museum Infinitum. If you killed him, you must progress the round to let him respawn. |
|
| 2 | Kill Oscar with the Rocket Ship |
 Go to the Rocket Ship and wait for Oscar to get behind it. Activate the ship once he is in place and try to hold him there to destroy him with the final blast. |
|
| * | Collect Another Set of Fragments if You Fail |
| If you failed to kill Oscar via the Rocket Ship, you can still redo the Rocket Ship in the same round as long as you get another set of 3 Absolute Zero Fragments. | |
| 3 | Pick Up the Shiny Trinket |
| After Oscar is destroyed, grab the Shiny Trinket Tactical that drops. |
Kill Oscar with the Luminarium Trap (Electro-Volt Projector)
| 1 | Lure Oscar to the Luminarium |
|---|---|
 Have Oscar follow you to the Luminarium (the western room with Jugger-Nog). If you killed him in the current round, you will need to advance to the next round for him to respawn. |
|
| 2 | Activate the Electro-Volt Projector Trap |
 Interact with the Electro-Volt Projector Trap in the middle of the room. You will need the car battery to activate it. |
|
| 3 | Wait for Battery Overcharge |
 Stay in the Luminarium with Oscar and survive until the battery overcharge completes. Once it finishes, Oscar will be instantly destroyed. |
|
| 4 | Get the Shiny Trinket |
 After Oscar is destroyed, again grab the Shiny Trinket Tactical that drops. |
