Call of Duty’s 2024 Season 3 Store lineup included three unusual Operator cosmetics: Tracer Pack: Stoney Sloth, Tracer Pack CODasaurus Ultra Skin and Tracer Pack: Big Brain Ultra Skin. The headline’s “brain in a jar” is a description used by Insider Gaming, not the official pack name.
Which skins does the headline refer to?
All three were Operator cosmetics offered through the Call of Duty Store during the Season 3 cycle associated with Modern Warfare III and Warzone in 2024. Activision’s official Season 3 announcement names the packs; the characters are distinguished by their concepts:
| # | Preview | Product | Price | |
|---|---|---|---|---|
| 1 |
|
McFarlane Toys- Call of Duty Burned Spawn 7in Action Figure | $26.88 | Buy on Amazon |
| 2 |
|
Exquisite Gaming Call of Duty Ghost Warzone Licensed Controller Holder & Phone Stand | $29.99 | Buy on Amazon |
| Official pack name | Character concept |
|---|---|
| Tracer Pack: Stoney Sloth | Sloth Operator cosmetic |
| Tracer Pack CODasaurus Ultra Skin | Dinosaur-themed Operator skin |
| Tracer Pack: Big Brain Ultra Skin | Brain-themed Operator skin, described as a brain in a jar in the headline story |
When and where were they offered?
Insider Gaming reported on March 27, 2024 that the packs were upcoming. The official announcement previewed Store offerings ahead of Season 3, which began April 3, 2024, across Modern Warfare III, Modern Warfare Zombies, Warzone and Warzone Mobile. The announcement also pointed readers to a further showcase on April 2.
These were Store cosmetics, not items the cited sources say were included with a physical copy of Modern Warfare III. The captured sources do not establish a current price, present-day Store availability, or whether a particular game edition grants access to any pack. Treat the names and timing as historical Season 3 information, not confirmation that the bundles can still be purchased.

Is this the 2026 Black Ops 7 Season 03?
No. This headline is about the 2024 Season 3 content cycle tied to Modern Warfare III, Warzone, Warzone Mobile and Modern Warfare Zombies. It is separate from Call of Duty: Black Ops 7 Season 03, whose patch notes are dated May 22, 2026. The shared season label does not mean the cosmetics belong to Black Ops 7.
Quick Recap
Rank #2
