See also: Bosses and Mini Bosses.

Mega Bosses are Ghosts that are more powerful than normal Bosses, and thus require more effort to defeat them. They have multiple attacks, and the Heavy Armor upgrade is ineffective against them. Similar to bosses, their health is displayed by percentage and not by an HP number. When fighting them, they will constantly have a shield that prevents them from being Vacuumed. You must use the Photon Blaster rewarded from the Gatekeeper(automatically given in Events if not yet unlocked) to damage their shield from afar. Once the shield is destroyed, they will be temporarily stunned and can be vacuumed or shot with the Photon Blaster to damage them.

Upon defeating the Mega Boss, you will be rewarded with the Boss' corresponding key, which can be used to open specific Boss Chests. The Player's Pack will also typically be filled to the biggest pack in that world (or in the Backdoor, the Player's Battery will be drained for 75,000,000). In Event Towers, a Player is awarded an Event Key when they defeat a Mega Boss on a floor. However, killing the Mega Boss by Photon Blaster will not yield the Ectoplasm, so it is recommended to vacuum on the last part to avoid this.

Mega Bosses[]

Normal Bosses[]

Event Bosses[]

Behavior[]

Mega Bosses have shields unlike normal Bosses, which prevent them from taking damage. The Player must destroy the shield using a Photon Blaster, which must be obtained from the Gatekeeper (with the exception of Event Mega Bosses, where it is automatically unlocked). Most mega-bosses automatically regenerate their shield whenever their health reaches 67% and 34%. When the shield is destroyed, Players are given a short window of time where the boss is stunned, allowing it open to taking damage before the shield is restored again. During this period, the player can also use Vacuum or Disruptor on the boss without having to use a Photon Blaster. In Events, the vacuuming speed for Mega Bosses is x2 faster.

Like Bosses and Mini Bosses, Mega Bosses have a health bar that is expressed as a percentage rather than with Ectoplasm, with 100% representing full health. Unlike Bosses, however, Mega Bosses can deal damage to the player. This damage is expressed as "Corruption"; with direct hits fillling the corruption meter, and when the bar is filled to 100%, the Player has been fully Corrupted and respawns outside of the Mega Boss' arena.

The only exception to this behavior is the Final Boss, where there is no Corruption at the exchange of there being a 20-minute time limit. You must also defeat all of its pillars and its Red-Green-Blue eyeballs before attacking the Final Boss itself.

Mega Boss Attacks[]

PLEASE NOTE: These will be divided into subcategories as each Mega Boss has their own unique attacks. Bosses also will not use specific attacks until they hit a certain health level

  • (All Mega Bosses) The mega boss will chase after a random player, and, upon making contact, will deal the player corruption damage
  • (All Mega Bosses) The boss slams down on the ground, causing the earth to shake. Anybody (within radius) that is not on a hoverboard will be thrown back and will be dealt some corruption damage.
  • (All Mega Bosses) The boss slams down on the ground, causing an explosion. Anybody (within radius) will be thrown back. If on a hoverboard, the hoverboard will unequip and the player will be thrown back

The Great Guardian[]


  • The Great Guardian lifts its hand up and grabs a random player with a tractor beam. If the player has a hoverboard equipped, they will be pulled in quickly and will be dealt with corruption damage. If the player does not have the hoverboard equipped, or deactivates it while being pulled in, then the tractor beam will drag them in much slower, allowing the player to easily escape it.
  • The Great Guardian slams the ground, causing white "blades" (that spin as they come outward) that swirl outwards from the mega boss. If hit by one of the "blades", the player is dealt damage
  • The Great Guardian shoots a purple laser from its eyes. The laser sweeps the area in front of the mega boss, but not in the back. When struck by the purple laser, the player will take corruption damage. Note that if the player doesn't move, the laser will lock on and deal consistent damage.


The Final Boss / The Developers[]

  • A beam shoots out from the final boss' eye, which knocks the player hit by it around. Does not deal corruption because there is no system of corruption in this boss.
  • It also summons some rocks and lava, and the players must climb the rocks to avoid being thrown around (the pillars sometimes glitch and slide you off, this is currently not patched and there is no definitive way to prevent it or the ghosts hit you and you fall of).
  • The boss throws its sword at the timer, freezing everything in place and turning the screen black and white. The boss then teleports to random players and slams them into the ground, stunning them until the boss does another attack. While it is possible to attack during this phase, your camera angle ALSO gets frozen. This could leave your camera at a bad angle, leaving you unable to attack.
  • The boss has a handful of sword attacks, and most are in his attack set for the entire duration of the fight. These include: throwing its sword up and causing a massive, hard to dodge sword rain that can easily destroy an entire team (from Phase 3 onwards), spinning with its sword in an attempt to hit random players, and throwing its sword around the edges of the arena in an attempt to catch players off-guard.
  • The boss leaps and strikes the ground with the sword in its hand (Phase 4 onwards, will jump twice more in Phase 5).
  • (Phase 5 only) It holds up the sword, the sword becomes massive and the boss will swing it left and right then strikes the middle.
  • (Phase 5 only) The boss uses its right hand to zoom in your camera by a large amount in an attempt to disorient players. The boss can do it a second time in a row and zoom in more.
  • (Until Phase 4) The boss will jump out of the arena, and a large amount of different-colored neon balls will roll from a random side in the arena. This attack is hard to dodge after the second phase, as you don't have your hoverboard or jetpack to quickly avoid them.


Boss Bo[]

  • Bo enlarges his tophat and spins towards a random player, dealing 10% corruption damage to any player that makes contact with it.
  • Bo's cane turns into the Great Guardian's hammer and slams the ground.
  • A large X of glowing green spans the entire floor and spins for several moments. As long as the player is on a hoverboard they will avoid corruption damage.
  • The Great Guardian's lasers appear above Bo's head and shoot 12 laser bolts at players.
  • Little Bo ghosts will appear and shoot green bolts, dealing the player corruption damage if hit.
  • Bo will tap his cane and large splotches will appear on the ground, glowing red then bright green. Splotches will deal corruption damage if they appear under a player, or if a player flies over a patch on a hoverboard. Patches will fade away after a little while.
  • Bo's cane will enlarge and sweep the room, first from side to side, then up to down, dealing corruption damage if you're in range.

Remnant Guardian[]

HP goes down 1.5x as fast, but shield regeneration time MAY be 15s instead of 10s.

  • Remnant Guardian shoots 40+ ultra homing orbs at the Players’ positions that arc until they land and explode, dealing damage to the player based on distance to explosion.
  • Remnant Guardian shoots a purple laser from its eyes. The laser sweeps the area in front of the mega boss, but not in the back. When struck by the purple laser, the player will take corruption damage.
  • Remnant Guardian punches the ground causing a shock wave to go across dealing 15% damage to and knocking players hit.
  • Remnant Guardian rushes at a player doing 7% damage and knocking players back on contact.
  • 15 massive orbs drop from the sky, damaging based on proximity and knocking players down if in range.
  • Remnant Guardian jumps into the sky summoning some rock pillars for players to stand on to avoid a rising lava layer that will do damage over time to players touching its surface.
  • Remnant Guardian teleports behind a player, hitting them with their axe for 7% corruption each, this happens 3 times. May get chained into remaining hits if not dodged.
