Zombies in Spaceland remains one of the most memorable round-based experiences in Call of Duty: Infinite Warfare, blending retro 1980s theme park vibes with complex Easter egg mechanics. Completing the main quest requires careful preparation, resource management, and execution of several puzzle sequences. Players looking to beat the alien boss and destroy the UFO must follow a precise sequence of steps to survive the ordeal.
Powering Up the Park and Unlocking Pack-a-Punch
The first major goal is turning on power switches across four distinct zones: Cosmic Way, Journey into Space, Kepler System, and Polar Peak. Activating these power portals allows players to open the central Pack-a-Punch portal located near the main fountain. Upgrading your weapons early is crucial for handling the increased difficulty of mid-game zombie waves.
While unlocking portal connections, players should also gather core utility items such as the DJ's boombox pieces. Keeping up with daily gaming news often reveals classic Easter egg tips that streamline early-round setups. Building powerful Wonder Weapons, such as the Dischord or Shredder, will make subsequent steps significantly easier.
Assembling N3310 and the SET-COM Parts
To initiate the main questline, players must interact with DJ N3310 to assemble the SET-COM device. The three required components—the Calculator, Boombox, and Umbrella—spawn in various randomized locations around the park. Once all three parts are delivered, N3310 will assemble the device and return it to the players after a brief delay.
After picking up the completed SET-COM, players must place it at three specific defense locations indicated by controller vibration. Each placement triggers a timed defense phase where horde waves focus on destroying the device. Using Traps, Sentry Turrets, and explosive weaponry ensures the SET-COM remains intact through all three defense rounds.
Mastering the Simon Says Color Puzzle
Returning the SET-COM to N3310 initiates the final confrontation prep, prompting speaker setups near the main portal. Four colored speakers corresponding to red, blue, yellow, and green must be placed around the central arena. The game will play a light and sound sequence that players must memorize and repeat in exact order.
Failing the color sequence spawns a Brute zombie and resets the puzzle attempt for that round. Communicating colors clearly with teammates or writing down the order helps avoid costly mistakes during high-pressure moments. Successfully matching the sequence three times summons the Alien Boss into the park.
Defeating the Alien Boss and Destroying the UFO
The Alien Boss battle requires players to continuously circle the arena while dealing damage to the alien's chest shield. When the alien's health depletes, it will kneel down and reveal a glowing fuse on its back that must be melee-attacked. Repeating this process twice destroys both fuses and finishes off the boss.
Once the alien falls, collect its dropped key and place it into the Pack-a-Punch machine to unlock the final step. Players must then shoot the five glowing targets on the park entrance archway using upgraded Wonder Weapons. Aligning the laser beam with the overhead UFO destroys the ship, officially completing the Zombies in Spaceland main Easter egg quest.
