TMNT: Splintered Fate has received Shell Squad Co-Op, a free update that substantially expands multiplayer teamwork. Super Evil Megacorp has also released the paid Trench Coat Pack, a cosmetic add-on inspired by one of the Turtles’ most recognizable disguises.
Shell Squad Co-Op: release date and key details
- Release date: November 10, 2026.
- Update price: free for everyone who already owns the game.
- Additional content: Trench Coat Pack, a paid cosmetic DLC.
- Supported modes: local co-op and online multiplayer.
- Game platforms: Nintendo Switch, Nintendo Switch 2, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and PC.
The update does not add a separate campaign or a new playable character. Instead, it is designed to make a four-player run feel more like a coordinated team effort and less like several individual adventures happening on the same screen.
What does the TMNT: Splintered Fate update add?
Shell Squad introduces 24 co-op powers, with three added to each power tree. These abilities can share effects, heal the group, or create combined attacks. For example, Passing the Torch gives the first teammate you touch the Rapid Fire effect, while Shared Warmth heals the entire team when one player uses a Splinter revive.
The update also brings eight co-op tools. Some link two characters with a beam that damages enemies caught between them; others create bubbles, freeze opponents, or grant temporary protection. On top of that, the game receives eight co-op masteries, one for every currently available character.
New masteries for Leonardo, Raphael, Donatello, and Michelangelo
- Leonardo: activating his special attack gives Light Shell to the nearest teammate.
- Raphael: critical hits from any player can become multiple critical strikes.
- Donatello: using his tool temporarily makes the closest ally invulnerable.
- Michelangelo: his special attack grants a stack of Torrent Strike to both himself and the nearest teammate.
Those four abilities are examples from the larger system. The downloadable characters also receive their own co-op masteries, giving established squads a reason to reconsider their preferred lineups.
Players can now switch characters during multiplayer
One of the most useful additions is the ability to switch characters during local and online co-op sessions. A group can reorganize without abandoning its run, making it easier to test different combinations during the same play session.
Shell Squad also improves Lucky Dice communication and refreshes several flame effects. These are smaller adjustments than the new powers, but they should make busy multiplayer battles easier to read.
Trench Coat Pack brings back a classic disguise
The paid content released alongside Shell Squad is purely cosmetic. The Trench Coat Pack dresses the Turtles and the additional playable characters in coats and hats. It does not change statistics or provide gameplay advantages.
The choice carries plenty of nostalgic weight. Trench coats have followed the Turtles through comics, animated series, movies, toys, and games for decades. The joke has always been as ridiculous as it is charming: four humanoid turtles trying to blend into a crowd with nothing more than hats and oversized coats.

Is it worth returning to Splintered Fate?
For solo players, Shell Squad does not overhaul the core structure of the adventure. Its biggest impact is felt by groups playing locally or online, where the new abilities create shared decisions and combinations that did not exist before.
That makes this update a strong reason to reunite the team, especially for players who have already finished the main story or explored the Alopex, Slash, and King’s Gambit content. The Trench Coat Pack is optional and aimed primarily at fans who enjoy classic TMNT visual references.
What comes next for TMNT: Splintered Fate?
Super Evil Megacorp ended its announcement by teasing “even bigger surprises” for 2027. The developer has not confirmed an expansion, sequel, new character, or additional story chapter. Anything more specific would be editorial speculation at this point.
The official Super Evil Megacorp update on Steam includes the complete list of changes. Shell Squad Co-Op and the Trench Coat Pack have been available since November 10, 2026.
