|Bullet Kin||Slowly walks towards the player, firing bullets.|
|Bandana Bullet Kin||Slowly walks towards the player, rapidly firing bullets.|
|Red Shotgun Kin||Slowly walks towards the player, occasionally firing a tight spread of 5 bullets. Has a chance to fire 6 bullets in all directions upon death.|
|Pinhead||Walks towards the player and explodes upon death. IF the player gets too close, it will leap towards the player and explode.|
After the first teleporter, go up one room and left two rooms. Defeat the bullet kins and find a crack in the lower wall. Use a blank near the crack to reveal a hidden room containing Old Knight's Shield, Old Knight's Helm, and Manny's corpse. If the player loots the shield and defeats the boss, Manny will claim that the player now knows his secret and reveals a backstory.
- If the player dies in the Hall of Knowledge, they will be revived in the previous room with max ammo and full health.
- The Robot, The Cultist, The Bullet, The Paradox and The Gunslinger cannot access the Hall of Knowledge because it is boarded off.
- Refusing to kill the first Bulletkin by firing all 1000 rounds of the Pea Shooter into a wall takes several minutes and forces the player to kill it with rolls. There's unfortunately no secret dialogue for doing this.
