Main Quest · Zombies in Spaceland

Sooooul Key

Spaceland’s main quest — spelled "Sooooul Key", four o’s, in the achievement list — is the first reel of Willard Wyler’s anthology: build the Seti-Com, hand it to the park’s DJ (David Hasselhoff, as himself), defend it three times, and answer a UFO’s color-coded Simon Says on four giant speakers. The saucer’s alien crew comes down to object, their punched-off fuses enable double Pack-a-Punch, and the finale shoots out the Spaceland sign’s lights to bring the UFO down — dropping the first piece of the Soul Key. Soloable; the lasting reward is Hasselhoff as a playable character.

Preparation

Before you start

Prerequisites

  • • Pack-a-Punch open (all four zone portals used)
  • • The four UFO trap-discs activated from the Projection Room
  • • An upgraded Weapon of Rock for the finale

Walkthrough

Step by step

  1. 01

    Build the Seti-Com

    Find the Boombox, Umbrella and Calculator among their spawn points and bring them to the ’Hoff, who assembles the device.

  2. 02

    Three defenses

    Place and defend the Seti-Com at three sites against timed assaults — one per round, with a Brute as the price of failure.

  3. 03

    Place the speakers

    Return the Seti-Com for the four speakers and set them on the golden symbols around the main portal.

    Warning: Interacting with the speakers commits the game — this is the point of no return.

  4. 04

    Simon Says

    Repeat the UFO’s flashed color sequences on the speakers, three rounds running; mistakes summon Brutes.

  5. 05

    The aliens

    Fight up to four aliens — collar lights track their health; when one crouches, melee its back to knock off an Alien Fuse, then finish it. Slot both fuses into Pack-a-Punch.

  6. 06

    Shoot down the UFO

    With an upgraded Weapon of Rock, shoot the five blue lights on the Spaceland sign — the last as the UFO passes — and collect the Soul Key piece it drops.
