Core Eject Shotgun
Weapon · WeaponShotgun3★[ULTRAKILL Collab] Heat drives this shotgun, so the shots never run dry. Equipping it swaps the Pal Sphere throw for Core Eject, which charges on a hold for extra range, and any core struck by Marksman Revolver fire detonates.
Core Eject Shotgun is 11th of 40 shotguns by attack, at 517 against the 1,400 of Prototype Shotgun.
This is where the crafting chain ends — nothing downstream consumes it, so a stockpile earns you nothing.
Details

Where to Find Core Eject Shotgun
Core Eject Shotgun is not something you find lying around — you craft it, and the recipe is below.
Every Tier of Core Eject Shotgun
The same piece exists at 5 rarities, and the gap is not cosmetic: attack runs 230 to 575, a 2.5x swing. Which one you end up with is decided by the rarity of the schematic you built from, not by the recipe — so a legendary copy of this is worth more than the next item up built from a common one.
| Rarity | Item | Attack | Durability |
|---|---|---|---|
| 0★ | Core Eject Shotgun | 230 | 150 |
| 1★ | Core Eject Shotgun | 402 | 225 |
| 2★ | Core Eject Shotgun | 460 | 300 |
| 3★ | Core Eject Shotgun (this one) | 517 | 450 |
| 4★ | Core Eject Shotgun | 575 | 600 |
Ammunition Core Eject Shotgun Uses
Core Eject Shotgun fires Shotgun Shell, and nothing else — running dry mid-fight is the usual way this weapon lets you down, so keep the recipe unlocked before you rely on it.
| Ammo | Yield | Craft cost |
|---|---|---|
 Shotgun Shell | ×10 | Refined Ingot ×2, Gunpowder ×3 |
Schematics That Unlock Core Eject Shotgun
The Technology tree hands you the plain Core Eject Shotgun at level 56 for 5 Ancient Technology points, but nothing above that base version — the rarer builds are schematic-only. One schematic grants the recipe, and they are world loot — chests, boss Pals and the late-game pools — rather than anything you research. Higher-rarity copies of the same schematic raise the quality of what you end up crafting.
| Schematic | Rarity | Where it comes from |
