MACE Project is a Post-Moon Lord mini boss found in the Abandoned Lab. It is the final mini boss of the Abandoned Lab. It fires fireballs, bombs and lasers in the first phase, and summons fists to attack in the second phase. It is summoned by right-clicking its specific monitor in the Omicron Sector of the Abandoned Lab.
It drops the Lab Access Panel - 0, which deactivates some of the laser security systems, allowing access to Sector Zero, and the Patient Zero boss.
While MACE Project is alive, the music Safety Violation will play.
Spawn
MACE Project does not spawn on its own and is only summoned by right-clicking the monitor in the Abandoned Lab's Omicron Sector, unlocked after defeating Protector Volt.
Behavior
Phase 1
MACE Project is initially stationary, hanging from the ceiling of the room. It will hit players with a variety of projectile attacks in a fixed order. The frequency and number of its attacks go up as it loses health.
- Roars, firing a ring of fireballs.
- Launches bombs that create lingering electric fields.
- Fires laser pairs and spreads of fireballs.
- Fires aimed pairs of green lasers in between attacks.
At low health (about 33%), a warning alarm will sound as MACE Project switches out its attack order.
- Shoots a large fireball that bounces around the room. After five bounces, it explodes into a ring of smaller fireballs.
- Fires a large number of bombs that create electric fields.
- Fires a large amount of fireballs at the player.
- Still fires pairs of lasers between attacks.
Phase 2
Upon its initial defeat, MACE Project's Jaw breaks off, leaving only the upper head behind. Its HP effectively refills, and it gains a new attack pattern. The order of its attacks is still fixed.
- Fires four pairs of lasers, along with a bouncing energy blast.
- Fires three rings of lasers.
- Moves along the rail at the top of the room, trying to line up with the player. After some time, it will slam down, emitting a shockwave that travels along the ground, along with a ring of electric bolts that may inflict Electrified.
- Fires numerous lasers while setting up a row of green orbs near the ceiling, which promptly create vertical laser beams. The locations of the beams are given away by flashing red warning lasers and a sound effect.
- MACE slams into one of the walls, creating a dense ring of electric bolts on impact.
Trivia

- MACE Project is a reference to M.A.C.E, the final boss of the video game Intrusion 2.
- a Copper-haired robot controls MACE Project in the upper right corner of the arena.
- This is the Crane Operator mentioned in Protector Volt's and The Janitor's quotes after defeating the boss.
