Read the pattern. End the fight.

The campaign has six major boss patterns. Each one is a short environmental or control puzzle; raw damage is rarely the real answer.

Short answerThe six fights covered here are Haybot, the Great Mighty Poo, the Boiler, Buga the Knut, the Experiment, and Heinrich. Watch for Context Zone prompts and scene-specific controls before assuming the PC release needs a patch.

All six campaign bosses

  1. 01

    Haybot

    Ride Franky and place a pipe between you and the incoming missile. Water briefly stuns the robot; move behind it and use the prompted action on the red back switch. Repeat with the remaining pipes.

  2. 02

    The Great Mighty Poo

    Keep moving while projectiles fall, then step onto the active Context Zone during the singing window. Throw toilet paper into the open mouth, move to the next platform, and repeat as the timing speeds up.

  3. 03

    The Boiler

    Stand on a corner floor marker and bait the Boiler onto the grate. Pull the overhead lever, use the prompted close-range action while it is stunned, then rotate to the next corner.

  4. 04

    Buga the Knut

    Stay mounted on the raptor, jump the ground shockwaves, and keep clear of the wide club swing. When the club is held overhead, attack from the front, circle behind, and use the second prompt.

  5. 05

    The Experiment

    Enter the tank immediately. Destroy the exposed weapon pair, separate the small arm target, then hit the red target on the Experiment’s back before it reconnects. Repeat for each weapon phase.

  6. 06

    Heinrich

    Use the space suit to punch until Heinrich is stunned. Grab the tail, build a spin, and release toward the airlock. Later rounds require shielding the counterattack before repeating the throw.

The repeatable rule behind each fight

These encounters fall into three patterns. Haybot, Great Mighty Poo, and the Boiler use the arena itself: bait an attack, activate a mechanism, then use the prompt. Buga uses a mounted opening. The final two fights replace normal campaign controls with a tank and a space suit.

  • Environmental stun: do not attack until the arena creates a visible opening.
  • Prompt timing: the light-bulb cue marks the action window; being close is not enough if the cue is absent.
  • Scene controls: tank, raptor, and space-suit controls override the normal movement set.

Common mistakes on the PC compatibility release

  • Starting with keyboard and mouse even though current input support is not clearly resolved. A controller is the safer baseline.
  • Standing next to an interaction point before the prompt appears.
  • Repeating direct attacks during an invulnerable phase instead of watching the arena mechanism.
  • Treating the lava race as a boss. It is a Uga Buga traversal sequence; return to the walkthrough route for chapter context.
