The ULTRAKILL crossover shipped free in Palworld's v0.7 "Home Sweet Home" update on 17 December 2025 and added four items across two tech-tree sets: V1 and V2 armour, the Marksman Revolver and the Core Eject Shotgun.
The basics
| Field | Detail |
|---|---|
| Announced | 23 September 2025 |
| Released | 17 December 2025, in v0.7 "Home Sweet Home" |
| Platforms | Steam, Microsoft Store, Xbox Series X|S, Xbox One, PS5 |
| Cost | Free update |
| New Pals added | None — this collab is gear only |
The same update brought the Hartalis raid boss, 48 new building parts including triangular pieces, Steam Workshop mod support on PC, and experimental PvP.
The two collab sets
| Set | Technology Level | Ancient Technology Points | Contains |
|---|---|---|---|
| ULTRAKILL Collab Set 1 | 32 | 3 | V1 Armor, Marksman Revolver |
| ULTRAKILL Collab Set 2 | 56 | 5 | V2 Armor, Core Eject Shotgun |
Both armour schematics are sold in the Arena Shop for 1,000 Battle Tickets each. No wandering merchant stocks them. If you have never touched the Arena, that is the gate — not the tech points.
V1 Armor
| Stat | Common | Legendary |
|---|---|---|
| Defense | 51 | 608 |
| Health | 806 | 2,112 |
| Durability | 1,450 | 72,000 |
| Weight | 30 | 30 |
| Resistances | Cold Lv.1, Heat Lv.1 | Cold Lv.2, Heat Lv.2, plus Attack Up |
The reason to wear it is Blood Is Fuel: it heals you when you deal damage. Nothing else in Palworld's armour list does that, which makes it a genuine alternative to simply stacking defence for aggressive play.
- Common craft: 30 Ingot, 15 High Quality Pal Oil — 800 workload
- Legendary craft: 270 Ingot, 85 High Quality Pal Oil, Ancient Civilization Parts — 120,000 workload, requires V1 Armor Schematic 4
One set of figures gives 15 Ancient Civilization Parts for the legendary V1 Armor; another gives 5. We could not resolve which is current, so budget for 15 and be pleasantly surprised.
V2 Armor
| Stat | Common | Legendary |
|---|---|---|
| Defense | 600 | 750 |
| Health | 215 | 1,900 |
| Durability | 19,000 | 72,000 |
| Weight | 30 | 30 |
| Resistances | Cold Lv.2, Heat Lv.2 | |
V2 trades the gimmick for the numbers: no lifesteal, but far higher defence at common rarity than V1 reaches until it is heavily upgraded.
- Common craft: 40 Plasteel, 40 Pal Metal Ingot, 20 High Quality Cloth — 4,000 workload
- Legendary craft: 270 Plasteel, 202 Pal Metal Ingot, 80 High Quality Cloth, 15 Ancient Civilization Parts — 120,000 workload
Which armour should you use?
Measurably: V2 has the higher defence at every comparable rarity, so it is the safer choice for raids and tower bosses. V1 is the better choice when you are the one dealing sustained damage, because Blood Is Fuel converts your damage output into effective health — a benefit that scales with how aggressive your build is, not with the defence number.
The weapons
| Weapon | Attack | Durability | Ammo | Craft |
|---|---|---|---|---|
| Marksman Revolver | 250 → 625 | 400 → 2,400 | Handgun Ammo, infinite magazine | 60 Ingot, 15 High Quality Pal Oil, 1 Gold Coin, 30 Electric Organ — Weapon Assembly Line, 800 workload |
| Core Eject Shotgun | 230 (Common) | 150 | Bottomless magazine | 80 Pal Metal Ingot, 65 Plasteel, 32 Carbon Fiber, 40 Flame Organ — Weapon Assembly Line II, 4,000 workload |
Both weapons hijack your Pal Sphere throw
This is the collab's cleverest idea and the thing that surprises people mid-fight.
- Marksman Revolver equipped: throwing becomes Coin Toss. Shoot a coin and the bullet ricochets at an enemy. Up to four coins can be airborne, replenishing one at a time.
- Core Eject Shotgun equipped: throwing becomes a Core Eject projectile that detonates on landing — or instantly if shot. Hold fire to charge for range.
Fire a core with the shotgun, swap to the Marksman Revolver, shoot the core mid-air. The revolver detonating shotgun cores is an explicitly designed interaction, not a bug — it is ULTRAKILL's own coin-shooting language ported into Palworld.
For the Marksman Revolver, the uncommon, rare and epic variants are currently unobtainable. For the Core Eject Shotgun, only the common rarity is obtainable at all. Do not plan a build around upgrade tiers that cannot be reached.
Is it still obtainable?
Yes, as of 13 August 2026. Everything above is gated behind evergreen systems — technology levels, Ancient Technology Points and Arena Battle Tickets — with no event window recorded anywhere. The strongest signal is that both weapons had their material costs reduced in version 1.0: Pocketpair was tuning them for the full release, not sunsetting them.
One third-party site describes the crossover as limited-time while simultaneously saying the sets remain craftable in 1.0. That is self-contradictory, and no official announcement or reference listing supports the limited-time claim.
