Call of Duty Infinite Warfare introduced a fresh take on the cooperative undead experience with Zombies in Spaceland, a vibrant 1980s theme park filled with deadly traps and hidden secrets. Navigating this retro wonderland requires players to balance power management, ticket collection, and quest progression. Mastering the map structure and completing the main quest allows players to defeat the alien boss and survive high rounds.

Opening the Park and Restoring Power

Surviving early rounds in Spaceland begins with activating power generators scattered across five key zones. Players must navigate through Cosmic Way, Journey into Space, Polar Peak, Kepler System, and Astrocade to power up perks and traps. Turning on all generators is essential for unlocking the central portal and accessing the Pack-a-Punch machine.

Once power is active, players can utilize portals located near each major area to fast travel back to the main hub. Stepping through all four peripheral portals activates the main portal in Cosmic Way. Entering this rift takes players to the Projection Room, where weapons can be upgraded for extra damage.

Building Wonder Weapons and N33L

To survive the main Easter egg quest, crafting unique Wonder Weapons like the Dischord, Shredder, Head Cutter, or Face Melter is highly recommended. Each pistol requires specific souvenir coins dropped by zombies and special items obtained around the park. Combining these elements creates powerful elemental sidearms capable of clearing large hordes instantly.

Players should also construct N33L, the robot companion, by gathering his missing battery, floppy disk, and head. Fulfilling N33L's challenges rewards players with tickets and assists during intense rounds. Calling in David Hasselhoff via N33L provides crucial fire support and revival aid during boss fights.

Set-Com Assembly and Simon Says Puzzle

Initiating the main Easter Egg requires speaking with the DJ in the booth across various areas to trigger the Set-Com questline. Players must gather three hidden components, including the calculator, boombox, and umbrella, to build the device. Delivering these parts to the DJ prompts him to give you the assembled Set-Com for defense steps.

Placing the Set-Com in designated locations around the park triggers timed defense waves where players must protect the device from aggressive hordes. Completing three successful defenses allows players to trigger the ultimate Simon Says color puzzle at the central portal. Memorizing and inputting the exact light sequences correctly unlocks the alien encounter.

Defeating the Alien Boss and Soul Key Retrieval

The final showdown pits players against a formidable Alien Boss who spawns near the Pack-a-Punch portal. Players must dodge powerful energy blasts while damaging the boss until his shield drops. Melee attacking the glowing fuse on the alien's back twice permanently defeats the threat.

After defeating the alien, players must destroy the massive UFO hovering above the park using the archway lights. Correctly timing the trap activation destroys the ship and drops the coveted Soul Key. Collecting this artifact completes the main map Easter egg and earns permanent rewards for future playthroughs.
