Rocket Ride to the first room. It's straight ahead, turn left once you hit the wall.

On entry there will be four Cerberus that spawn in a straight line blocking the entrance. Before they spawn, place a magnet in the center and spam Sawblades, then hit them all with a Nuke. A Ferryman should spawn once two of them are dead. Two Virtues should spawn once all four Cerberus have been killed. These Virtues are outside the room, so you need to kill the Ferryman as quickly as possible

before moving onto the Virtue's room. This doesn't have its separate category because it's not a challenge. Shotgun swap or Revolver them.

• It might seem difficult to move, so use dash invincibility frames as much as possible, or just parry.
  
• Try not to be overwhelmed by the Enraged state of the Cerberi.

Mostly crowd control with a new bad egg: An invincible Mindflayer that follows you wherever you go. Remember to deal with it whenever necessary.

• Parry the Mindflayer's projectiles to gain your HP and Stamina back.
  
• Worry about the Sentries and the Swordsmachine first. Trust me.

Not so much a room as it is a hallway. Cramped space mixed with a single Cerberus at the end of the hall and two Streetcleaners willing to back you up. The Mindflayer is still here, too.

• Use an overpump and shotgun swapping to take out the Cerberus quickly. Then do what you want with the Streetcleaners.

The run-killer of them all. It might seem difficult... And it is, but don't worry.

• Even if the concept of two Mindflayers overwhelms you, do not stress out. It's very easy to use a Mindflayer's weapons against another enemy, and even if you're still worried, attaching a Screwdriver to an Idoled Mindflayer will still stop it from teleporting.
  
• Malicious Faces can easily be taken out with a Shotgun + KB > Shotgun combo up close. Virtues can be taken out with an Overpump and another Shotgun + KB hit, or just a single Electric Railcannon shot.
  
• The second the Idols are vulnerable, heal. Heal as much as you can, because two Mindflayers are difficult to deal with for a regular player.

So, there are two Insurrectionists, right? Well, an easy way to get rid of one is to perform a Scrongled:

• Launch a rocket and ride it above one of the spawn areas that the Insurrectionists jump from.
  
• Wait until the second Insurrectionist jumps out of (and back into) spawn area.
  
• Make sure you don't get hit by it.
  
• Anyways...
  
• You can parry an Insurrectionist's attacks or launch an S.R.S. at it to briefly knock it down.

This is a very weird room. The walls will deal a flat 30 damage if you are to touch them, so try not to hit them.

There are two Virtues, two Malicious Faces, and one Sentry in the first section - and two Cerberi, two Sentries, and one Malicious Face in the second.

• Hit 'em with a nuke to make sure that they're all dead the second you enter the first room. The knockback should push the Virtues to the walls, but if it doesn't, just coin or shoot them manually.
  
• Keep to the center. Don't veer off to the sides unless necessary. You should have enough style points by now.

Probably the hardest room out of them all, besides the Prime Soul.

There's an Idoled Stalker that will constantly sand enemies without dying. Take out as many of them as you can, and if possible, launch it into the air before it explodes to avoid Maximum Sandage.

• If you quickly Electric Railcannon two Sentries and them off, you only have half the treat to deal with.
  
• Place a magnet in the middle of the room when the enemies begin to spawn, similarly to the first Weezer room, to deal damage to most of the enemies easily.

The most important thing to note is that when the yellow bar depletes, regardless of Flesh Panopticon's health, this phase will automatically transition into the final boss fight.
So don't feel pressured to take out all the eyes as soon as possible.

Other than that, just use the same strategy as you did last time with Flesh Prison.

Attacks

• Mortars: Shot diagonally into the air, they track the player. Deals 60 damage per shot.
  
• Divine Beams: Like Flesh Prison, but now they can be Horizontal. 30 damage.
  
• Black Hole: bro...
  
• Miniface Beams: bro... 20 damage.
  
• Miniface Explosions: bro... 50 damage.

• UNDER CONSTRUCTION

Have fun.

Okay, seriously, Sisyphus isn't as bad as he turns out to be. It's mainly memorisation and parrying.

• "Be gone!" - Overhead that creates a vertical shockwave [parryable]. 30 damage.
  
• "Destory!" - Uppercut that combos into setting a timed explosion at the player's position [start-up of timed explosion is parryable]. 33 damage.
  
• "You can't escape!" - Four punch combo, creates a shockwave after final punch [final punch is parryable]. 30 damage each.
  
• "This will hurt..." - Creates a large area-of-effect explosion [parryable] {parrying will cancel the explosion}. 50 damage.
  
• Meteor (No Voice Line) - Straight-down ground slam [hitscan, not parryable]; creates a shockwave after landing. 30 damage.
  
• Spinning Kick (No Voice Line) - Launches the player into the air if hit [parryable]. 30 damage.
  
• Downward Swing (No Voice Line) - Launches the player into the ground if hit [not parryable]. 30 damage.

• If Sisyphus Prime leaves your field of vision, he is in the air doing his meteor.
  
• Sisyphus Prime is more likely to use his spinning kick if you're in the air.
  
• Sisyphus Prime is likely to combo his downward swing into a meteor.
  
• Sisyphus Prime is likely to combo his spinning kick into "Be gone!".
  
• The player can still take damage after Sisyphus Prime is killed during his dialogue if hit by a shockwave or explosion.
