Step 1
Pack-A-Punch
Activate the Power and the Portal, then go through the Portal for all 4 locations:
- Journey Into Space — Astrocade
- Journey Into Space — Rover Rampage
- Triton — Polar Peak
- Kepler — Moonlight Cafe
Pack-A-Punch will now be accessible via the Portal in the Cosmic Way.
Step 2
Build the Seti-Com
Collect 3 parts. Each area listed can only have one part (marked I, II, III):
- Boombox:
- Cosmic Way — under the Infinity Bridge, on a cart
- Kepler — Moonlight Cafe countertop
- Underground — Coffee Room, on the countertop
- Calculator:
- Cosmic Way — near the Pack-A-Punch Portal, on a bench
- Kepler — on a yellow table near the Chromosphere
- Journey Into Space — Astrocade upstairs, on a trash bin
- Umbrella:
- Cosmic Way — bottom of Hyper Slopes, on a bench
- Triton — Polar Peak Gift Shop, on the countertop
- Journey Into Space — corner near the Star Mission trap control panel
Give the 3 parts to Hasselhoff:
- Journey Into Space — next to Mule Munchies
- Triton — outside the gift shop
- Kepler — next to the Octonian Hunter game
End the round and wait for the UFO on Triton to make noise, then take the built Seti-Com from Hasselhoff.
Step 3-6
Seti-Com Defenses & Speakers
Place and defend the Seti-Com 3 times at one of 7 randomly chosen locations. Your screen will start shaking when you're near the correct location.
Repeat this 2 more times (3 total), ending the round to start the next defense. Each time, the defense duration increases by 30 seconds.
After the 3rd defense, give the Seti-Com back to Hasselhoff, then progress 2 rounds (excluding Clown Rounds).
After progressing 2 rounds, take the Speakers from Hasselhoff.
Place the 4 Speakers on the Golden Circles around the Cosmic Way Pack-A-Punch portal.
Possible Seti-Com Defense Locations
- Journey Into Space — next to the Escape Velocity Trap
- Journey Into Space — outside Rover Rampage
- Underground — Coffee Room
- Cosmic Way — across the bridge in front of Triton
- Triton — inside the Gift Shop near the Yeti Trap
- Triton — Water Fountain area
- Kepler — next to the Crocodile Trap near the ERAD wallbuy
Warning
If you fail a defense, you need to get a new Seti-Com from Hasselhoff.
Speaker Order
The order you place the 4 Speakers determines their color: Yellow, Blue, Green, Red (in placement order).

Final Steps
Boss Fight
Every player interacts with a different Speaker at the same time to start the boss fight.
Play Simon Says with the Speakers and UFO 3 times. The UFO flashes a sequence of 4 colors — interact with the Speakers in that order quickly.
After each round, wait about a minute for the UFO to give the next sequence. If you fail, a Brute spawns.
After the third round of Simon Says, defend against 100 Clowns.
After killing the 100 Clowns, Alien(s) spawn — the number of Aliens equals the number of players.
Shoot the Aliens to knock them down. Once knocked down, melee the Battery on its back when it drops to its knees.
Break the battery twice on each Alien — the third time you damage them enough, they die. The lights on their chest go from green → yellow → red to indicate progress.
After all Aliens are killed, pick up the Alien Fuses from in front of Pack-A-Punch and place them into it. This allows you to Pack-A-Punch the Weapons of Rock.
Using a Pack-A-Punched Weapon of Rock, shoot the 5 lights around the Spaceland sign on the Infinity Bridge. Make sure to shoot the last light when the UFO is over the Pack-A-Punch Portal so a laser beam shoots it down.
Once the UFO is shot down, collect the Soul Key from in front of Pack-A-Punch to complete the Main Quest.
Tip
It's easier to have multiple players on different Speakers for the Simon Says step, but a single player can complete the sequence alone if needed.
Completion
If playing in Director's Cut, you can also collect the Talisman.
