Habroxia 2 (HP)

This may seem daunting at first, but if you choose the right loadout, and learn the bosses pathing after a few tries you'll nail it in no time. It was only a matter of time before every attempt I did he was a sliver. What makes or breaks your run is just how many times you got hit throughout the fight.

Start out by going to your upgrades, and selling everything till it says 0. Then go back to your ORIGINAL playthrough, and select the far right twinkle, "Odin, Galactic Chaos"

Now what I found to be the most OP loadout, was the laser weapon. Bomb worked for a short bit, but I found I missed shots more often then not. The laser is always a guanteed hit. Now what you wanna do is hold your RB button throughout the whole fight, keep that laser going as much as you can. Along with the bullets your shooting of course.
Why its so good, is because it stops some of the bosses shots, so theres moments you may find where can sit in 1 spot for a few seconds and chip away his health.

Another thing, make use of your DASH when you can. I probably knocked a quarter of his health away just from dash. Very good ability for this whole title update as a matter of fact. Never had something get me out of a pickle as much as the dash in this game.

Luckily it's only a 2 minute fight so it's not asking for much. Hope this helps!
Good luck!
