Mech Horizon

**Mech Horizon** is one of the two possible final bosses in Celestial Protocol. It is a giant robot controlled by Hyso.

## Appearances

Mech Horizon appears in Chapter 4 in the Wormhole Engines section if you choose to not spy for the Varkems.

## Boss Fight

The Mech Horizon will stand in the large hole in the middle of the arena. The player can only go around the boss on the area encircling it.

When there are no hands, the red cockpit can be shot at to damage it. The mech will pick a player to ‘target’, and it will be constantly be facing that player depending on where in the arena they are. It repicks a target every 30 seconds.

The mech suit uses the following attacks. When about to use an attack the arena segment that it is targeting flashes red. It gains more attacks and replaces some with attacks which are more tricky in terms of where in the arena they can hit.

* Laser Volley - Its head will charge up, then unleash a deathly volley of red laser shots forward. They will land at various targets on the four segments in front of it (a quarter of the arena).
* Sweeping Laser - It shoots a sweeping laser that sweeps specifically along the segment of the arena it is facing. Players ought to run from it. It covers the four segments in front of it. This attack only happens in Phase 1 of the fight (i.e. no horizon weapons have been spawned)
* Exploding Volley - It shoots a boatload of purple exploding shots from above, which hit the four segments in front of it. He is doing this attack only until horizon repulsor/cannon spawn.
* Dual Sweeping Laser - It shoots two sweeping lasers that start from the sides and close in on each other. Together they cover the six segments in front of it. This attack only happens in Phase 2 of the fight. (i.e. after the horizon gauntlet and horizon laser have been defeated for the first time)
* Alternate Exploding Bombardment - Many purple exploding shots come down from above above a random set of segments. This attack only happens in Phase 3 of the fight. (i.e. after the horizon repulsor and horizon cannon have been defeated for the first time)
* Mega Laser - It shoots one laser in the middle which splits off into two balls of red energy that travel along the arena. Overall it covers the eight segments in front of it. This attack only happens in Phase 4 of the fight (after all four horizon weapons have been fought at the same time)
* Entire Exploding Bombardment - Many purple exploding shots will hit every segment except for the two directly in front of the Mech. This attack only happens in Phase 4 of the fight (after all four horizon weapons have been fought at the same time)

While charging and unleashing any of these attacks, it will no longer turn, giving players an opportunity to move.

Some extra attacks also periodically get used as its health goes down.

* Below 75% health, its body can fire a ‘bullet hell’ of lots of damaging red blasts. These can either go from the body in all directions, or parallel across the arena from behind the Mech.

* Below 50% health, black holes can be form around the arena. These only spawn if no other black holes currently exist (so you can’t get two sets of black holes in a row).

When the Mech drops to certain percentages of its health for the first time, it will heal up and summon some Hands to attack the player. While Hands are summoned, none of its other attacks go, and the head cannot be damaged.

* At 75% health, the Horizon Gauntlet and Laser spawn for the first time.
* At 50% health, the Horizon Repulsor and Cannon spawn for the first time.
* At 25% health after a brief cutscene, all four hands spawn.

## Horizon Repulsor

### Attack Damage

12 (Slam/Beam)
6 (Phaser)

### Abilities

Inflicts Mining Fatigue III for 10 seconds (Slam)
Inflicts Weakness for 10 seconds (Slam

Each hand has two attacks that they alternate between.

### The Horizon Repulsor:

* Sometimes it lands on the ground and aims at the player before unleashing an immensely powerful blast from its palm.
* Or it can also slam the ground, emitting 16 shockwaves in the form similar to Utgy’s Shockwave Gauntlet.

## Horizon Gauntlet

### Attack Damage

24 (Punch)
12 (Slam)

### Abilities

Inflicts Mining Fatigue III for 10 seconds
Inflicts Weakness for 10 seconds

## Horizon Laser

### The Horizon Gauntlet:

* It can slam down in succession in a line. Slams emit large AOE shockwaves.
* Or it can hover in front of the player and then punch forward. When it punches forward, upon hitting a wall it emits a large AOE shockwave. After punching it may do another punch or go to do some slams.

## Horizon Cannon

### The Horzion Laser:

* It can hover between the mech and the player and emit a sweeping laser-ray, similar to Colonel Spanner.
* Or it can go and fly above a player and beam a laser downwards, kind of like the sky-laser attacks of some of the Varkem Mechs.

### The Horizon Cannon:

* It can either shoot a spread of rockets.
* Or shoot one homing rocket at a time.

Some larger Antimatter Orbs will spawn around the arena whenever a sets of hands are destroyed. These shoot green electric bolts at you.

## Recommendations

* Before it summons any hands, all of its attacks only attack the four segments directly in front of it, meaning staying at the diagonals of the arena can allow you to quickly move to a section that won’t go under attack.
* Later stages of the fight will require you to think a bit more, but again, most of them can be easily dodged by staying out of where they are about to hit.
	+ The only one that may be difficult to dodge is when it uses its Mega Laser, as that covers an entire half of the arena in front of it, and if you are nearly directly in front of it when it uses it, you may be unable to get to safety in time. However, using a Magnetic Repulsor, it is possible to jump over the laser blast.

* As for the bullet hells and black holes, listen for their sound effects and dodge accordingly. Sometimes a black hole may block you from avoiding a main attack, and you’ll end up needing to hope for the best.

The Cosmic Commando Phaser deals the most ranged DPS. You won’t need to be constantly dodging, unlike when fighting Hyso or the hands, which makes it a good choice for the head. It is also recommended for shooting down Antimatter Orbs that spawn.

* The Big Brain is very effective at dealing with the Antimatter Orbs, as it will latch onto one and then move on to the next one, eventually destroying all of them, so you can just focus on the Mech Horizon itself.

As for the hands, they will constantly assault you with attacks that will force you to stay on your feet.

* The Horizon Gauntlet is arguably one of the most aggressive hands, as it will constantly assail you with punches and slams. When it is about to punch you, you can dodge it by simply moving to one side, while when it is doing its slams, simply move along the arena away from it.
* The Horizon Laser isn’t too hard to dodge, even if you are trying to dodge other hands at the same time, but you should still be wary of it, especially if you find yourself needing to suddenly turn back due to where another hand’s attack is coming from.
* The Horizon Repulsor is very easy to dodge, and is actually barely a threat at all. You will need to keep moving to avoid its attacks, of course. And like the Laser, you could get caught by it if you find yourself needing to turn back.
* The Horizon Cannon, unlike the more varied nature of its counterparts, constantly stays at a distance and shoots exploding rockets at you. The homing ones will require you to raise your energy shield to block them, while when it shoots a spread of three rockets, you will need to either move to the side or use an energy shield again. It only shoots once every 4 seconds so you won’t need to block often, but it is often enough that you’ll need to be aware of it.

Rapid Blasters are the best weapons for the hands, especially if you can line up shots to hit multiple at once. In order, these are roughly how dangerous each hand is, and is hence the recommended order you should deal with them:

Horizon Cannon → Horizon Gauntlet → Horizon Laser → Horizon Repulsor

In the phase when all four hands are spawned, the Horizon Repulsor and Gauntlet can end up taking lots of damage from the explosions of the Cannon’s rockets, meaning you could take both out quickly and then deal with the Cannon, and lastly clean up whatever’s left.

The Nebula Orb and Sweeping Laser Turret can also deal large amounts of damage to the Gauntlet and Repulsor if you manage to get them within their area of attack. The Sky Laser Beacon can also deal massive damage.

* The Big Brain will not target them, and while the Orange Phaser Turret will shoot, its shots won’t deal any damage unless they hit the bottom of a hand (and it aims near the top).

## Notes

* Mech Horizon is one of the final bosses, the other final boss is the Supreme Celestipede.

* No Quarter by TeknoAXE plays during Mech Horizon boss fight.
