Call of Duty: Infinite Warfare introduced a retro-themed survival map that quickly became a fan favorite among zombie enthusiasts. Completing the main quest in Zombies in Spaceland requires coordination, precise timing, and a deep understanding of the theme park's unique mechanics. Players must work through a series of multi-step puzzles to summon and defeat the alien boss before escaping the park.
Restoring Power and Accessing the Pack-a-Punch
Before attempting any Easter egg steps, players must power up all four main sectors of the theme park. Once the power switches are activated, head to the central hub to open portals connecting each zone back to the main plaza. Entering every portal allows players to unlock the Projection Room, granting vital access to the Pack-a-Punch machine for weapon upgrades.
Assembling N33T-13 and Finding the SET-COM Pieces
The next phase requires rebuilding the N33T-13 robot stationed near the spawn building to earn DJ Hoff's assistance. Players must gather three hidden SET-COM components scattered around the map, including a calculator, a boombox, and an umbrella. Following daily gaming news often helps fans track down obscure item spawns and community strategies for speedrunning these initial setup phases.
Defending the SET-COM Defense Sites
After giving the assembled SET-COM to N33T-13, players must defend three distinct locations across the park from aggressive zombie waves. Each defense test increases in difficulty, making explosive weapons and upgraded sidearms essential for protecting the device. Successfully completing all three defense waves triggers the countdown to the final boss battle encounter.
Mastering the Simon Says Sequence and Alien Boss Fight
Once the SET-COM steps are finished, players must complete a memory-based color sequence on the main stage speakers. Matching the speaker notes correctly summons the Alien boss, who attacks with plasma blasts while spawning surrounding hordes. Defeating the boss requires dodging attacks, shooting his chest core, and melee-ing his exposed fuses twice to conclude the main story quest.
