Bullet Hell is an unlockable passive item in Fiend Folio: RELOADED, a mod for The Binding of Isaac.

While in an active room, orange targets periodically appear on the floor. When stepped on, Isaac shoots a radial pattern of bullets.

Up to 2 of these targets may be active at a time. Once they appear, they will not disappear until stepped on by Isaac.

There are 4 possible bullet patterns that are selected at random:
• 1) A ring of 12 bullets that deal DamageStat + 3 × CurrentStage damage.
• 2) A consecutively forming spiraling ring of 19 bullets that deal DamageStat × 1.2 + 2 × CurrentStage damage.
• 3) A pattern of 19 bullets that starts shrunk and quickly spirals outward, dealing DamageStat + 2 × CurrentStage + 6 damage.
• 4) 3 sets of 12 bullets in a rapidly spinning pattern, dealing DamageStat + CurrentStage damage.

Defeat Mega Satan as Friend.
