Checkpoint
CE Boost // DIFFICULTY: 1.5/10
Start off by sliding down the entrance while charging up the CE Shotgun. After the door starts opening, flick down and throw a core below you to do a CE Boost to boost up to the first door.
After boosting up to the first door, do another CE Boost to get to the next door. Once you're touching the floor, do a Slide Jump to hit both the checkpoint then the arena door. After hitting the arena door, checkpoint and enter the arena.
Lava Hall UB // DIFFICULTY: 3/10 // FASTEST
Start off by placing oil in the middle using the Firestart Rocket Launcher. Then, do a Slam Store (or two) and slide until you make it to the first door.
Once at the first door, slam down, then do a dash slide through it. After you're past the door, line up in the following spot below.

After doing an Ultraboost, quickly swap to the Firestarter Rocket Launcher and start placing oil when you're near the door to the arena.
Once close to the floor, start sliding while still placing oil til you hit both the checkpoint and open the arena door. After hitting the arena door, checkpoint and enter the arena.
Boss Kills
Saws + JS + Slarp // DIFFICULTY: 2/10
After checkpointing, do a DSJ into the arena while shooting out blue sawblades. As you're shooting out saws, place a magnet near both of the Cerberi. Make sure to place down all of your blue saws and an oversaw.
Once all of your saws are placed down, switch to your jumpstart and attach a cable on the first Cerberi as soon as it spawns in. After it spawns, equip your Slarp and use the alt fire on the Cerberi to deal extra damage.
Upon shooting, equip the Sawed-On Jackhammer and start charging up both the primary and alt fire. Once it's roughly finished, whiplassh the Cerberi then un-whiplash it, and once you're near the Cerberi, release both the primary and alt fire.
By this point, the Cerberi should be near death and it'll either die from the sawblades, or you'll need to do extra damage yourself such as by doing Projectile Boosts.
Once the first Cerberi is dead, throw a coin at the second Cerberi right before it spawns, then once it spawns shoot it with the Electric Railcannon and do an S.R.S. Combo.
After both Cerberi are dead, move onto the Arena Exits section and see which one you're able to do. Below will be a full demonstration of the kill.
Jackhammer + JS // DIFFICULTY: 3/10
After checkpointing, do a DSJ into the arena while shooting out blue sawblades. As you're shooting out saws, place a magnet near the first Cerberi.
Once you have around 7 to 9 blue saws and 1 oversaw placed, equip the Sawed-On Jackhammer then do a Dash Jump into the Cerberi as it spawns in and hit it with the Jackhammer. While in the hitstop, equip the Jumpstart and then attach a cable to the Cerb.
You'll be sent back after hitting the Cerberi with the Jackhammer. Once you're near the second Cerberi, equip the Freezeframe Rocket Launcher, freeze, and start firing rockets.
Do note that while you're firing rockets, you should parry the ball that the Cerberi throws at you so then it dies sooner. You'll also avoid the possibility of blowing up rockets and end up killing the Cerberi later (which is slower).
Upon firing three rockets, hop off the rocket by slamming, then go backwards, equip the S.R.S. Rocket Launcher and start charging it up. As soon as the second Cerberi spawns in, release the alternate fire and punch the cannonball to cannonboost or S.R.S. Combo both Cerberi.
After both Cerberi are dead, move onto the Arena Exits section and see which one you're able to do. Below will be a full demonstration of the kill.
Rocket + Jackhammer + JS // DIFFICULTY: 4/10
After checkpointing, do a DSJ into the arena while shooting out blue sawblades. As you're shooting out saws, place a magnet near the first Cerberi.
Once you have around 7 to 9 blue saws and 1 oversaw placed, equip the Freezeframe Rocket Launcher and place a rocket where the second Cerberi would spawn.
Afterward, equip the Sawed-On Jackhammer then do a Dash Jump into the Cerberi as it spawns in and hit it with the Jackhammer. While in the hitstop, equip the Jumpstart and then attach a cable to the Cerb.
You'll be sent back after hitting the Cerberi with the Jackhammer which results on you landing on your previously-placed rocket. Now, equip the Freezeframe Rocket Launcher again and start hold firing rockets.
Do note that while you're firing rockets, you should parry the ball that the Cerberi throws at you so then it dies sooner. You'll also avoid the possibility of blowing up rockets and end up killing the Cerberi later (which is slower).
Upon firing three more rockets, hop off the rocket by slamming, then go to the first Cerberi, equip the S.R.S. Rocket Launcher and hit it with a cannonball to kill it (in case it isn't already dead).
After both Cerberi are dead, move onto the Arena Exits section and see which one you're able to do. Below will be a full demonstration of the kill.
Rocket + SRS + Jackhammer + JS // DIFFICULTY: 6.5/10
After checkpointing, do a DSJ into the arena while shooting out blue sawblades. As you're shooting out saws, place a magnet near the first Cerberi.
Once you have around 6 to 7 blue saws and 1 oversaw placed, equip the Freezeframe Rocket Launcher and place a rocket where the second Cerberi would spawn.
Equip the S.R.S. Rocket Launcher, charge it up a little, and throw it up slightly upwards. Afterward, equip the Sawed-On Jackhammer then do a Dash Jump into the Cerberi as it spawns in and hit it with the Jackhammer. While in the hitstop, punch the cannonball, equip the Jumpstart and then attach a cable to the Cerb.
You'll be sent back after hitting the Cerberi with the Jackhammer which results on you landing on your previously-placed rocket. Now, equip the Freezeframe Rocket Launcher again and start hold firing rockets.
Do note that while you're firing rockets, you should parry the ball that the Cerberi throws at you so then it dies sooner. You'll also avoid the possibility of blowing up rockets and end up killing the Cerberi later (which is slower).
Upon firing three more rockets, hop off the rocket by slamming, then go to the first Cerberi, equip the S.R.S. Rocket Launcher and hit it with a cannonball to kill it (in case it isn't already dead).
After both Cerberi are dead, move onto the Arena Exits section and see which one you're able to do. Below will be a full demonstration of the kill.
