Chaos

Chaos ship is the final ship playable in the base game. It is unique in that it's Weapons change room by room.

Randomization
Every room, your weapon will change to a new one with two Keywords. This weapon is tied to that room, and if you leave the room and return you will always get that weapon while in that room, even across seeds.

Ammo
Ammo works slightly differently than normal when playing as arena blaster as ammo is displayed as a percentage instead of a concrete number. Different weapons use differing amounts of the ammo, with weapons that have less ammo with normal characters such as thunder head lowering the percentage more per shot than weapons such as Vulcan. When you run out of ammo, instead losing the current weapon you use the room's seeded weapon but stripped of all keywords. When in a breach you instead use the peashooter.
