Teenage Mutant Ninja Turtles: Splintered Fate King’s Gambit Update Adds Slash, Rat King and More

Summary:

Teenage Mutant Ninja Turtles: Splintered Fate has received one of its most significant expansions with The King’s Gambit, a free version 2.0 update that brings the game’s main storyline to its conclusion. Super Evil Megacorp has placed Rat King at the heart of the finale, giving experienced players a demanding new endgame encounter that becomes available after completing important objectives involving Shredder and Master Splinter. Defeating Rat King isn’t simply another victory to tick off either, as doing so unlocks a new ending and provides the finale to the main campaign.

The update also brings something considerably less terrifying to the Turtles’ Home Lair. Pepperoni, the pizza-loving dinosaur, joins the group as a new ally and is available to players as part of the free update. Alongside The King’s Gambit, Super Evil Megacorp has released several paid additions. Slash becomes the eighth playable hero, offering a slower but immensely powerful fighting style built around physical strength, knockback attacks, Water and Ooze affinities, and his temporary Enraged mode. His DLC also introduces five new Artifacts and a special Tool capable of causing a meteoric explosion.

Players can additionally pick up the Samurai Armor Pack, which provides warrior-inspired outfits for the original four Turtles and owned DLC characters. Those wanting the released extras together can instead look toward the Platinum Bundle, which combines the paid additions released so far with the game’s free updates. Super Evil Megacorp has also confirmed that support for Splintered Fate isn’t ending with version 2.0, while the retail Nintendo Switch 2 Legendary Edition remains scheduled for October 27, 2026.

Teenage Mutant Ninja Turtles: Splintered Fate’s King’s Gambit Update Brings the Main Story to Its Finale

Teenage Mutant Ninja Turtles: Splintered Fate has grown considerably since the Turtles first started battling their way through its roguelike take on New York City, and The King’s Gambit represents a particularly important point in that journey. Released as the game’s free version 2.0 update, The King’s Gambit completes the main story while giving both returning players and seasoned sewer-dwellers another reason to assemble the team. Super Evil Megacorp isn’t treating this finale like a quiet victory lap. Instead, the developer has introduced a new endgame threat, additional challenges and another familiar face for the Home Lair. It’s the kind of update that gives a long-running campaign a proper final obstacle rather than simply rolling the credits after another familiar encounter. For players who have spent run after run sharpening builds, learning enemy patterns and rescuing Master Splinter, that obstacle comes in the distinctly unpleasant form of Rat King.

Rat King Becomes the Ultimate Endgame Challenge for the Turtles

Rat King takes center stage as the major enemy of The King’s Gambit and serves as the final threat of Splintered Fate’s main storyline. Calling him another boss would undersell what Super Evil Megacorp has built around the encounter. Rat King waits inside his own realm at the end of a demanding run designed to test the combat skills players have developed throughout the campaign. Even getting into striking distance isn’t going to guarantee an easy showdown. Rat King can bring other powerful bosses into the fight and effectively turn previous major adversaries into backup, creating the sort of battle where losing concentration for a moment can quickly turn a promising run into turtle soup. Players will need to manage positioning, damage output, defensive options and whatever build they’ve assembled along the way. Victory has a meaningful reward beyond bragging rights, as defeating Rat King unlocks a new ending that closes out the game’s main campaign.

Reaching Rat King Requires Players to Prove Themselves First

You won’t be able to fire up Splintered Fate for the first time and immediately knock on Rat King’s door. The new finale is deliberately positioned as endgame material, and players need to satisfy progression requirements before the encounter becomes available. That includes defeating Shredder multiple times and successfully rescuing Master Splinter, ensuring that the road to Rat King comes after you’ve already demonstrated a solid understanding of the game’s combat loop. It’s a fitting approach for a finale built around the accumulated experience of repeated runs. Splintered Fate has always encouraged players to become stronger through both permanent progression and simple familiarity with its systems, so placing Rat King beyond those earlier achievements gives the showdown some weight. By the time you reach his realm, you’ve already survived plenty of Foot Clan trouble. Unfortunately for the Turtles, Rat King apparently looked at all that experience and decided they still hadn’t suffered enough.

Pepperoni Brings a Friendlier Addition to the Home Lair

Not everything arriving with The King’s Gambit wants to flatten the Turtles. Pepperoni joins the Home Lair as a new ally through the free update, providing an adorable counterbalance to the considerably more hostile Rat King. Fans familiar with the wider TMNT universe will recognize the little dinosaur, and her arrival gives players another friendly character to encounter between dangerous runs. The Home Lair already serves as a welcome breather where progression and character interactions break up the relentless combat, making Pepperoni a natural fit for that side of Splintered Fate. Super Evil Megacorp even gives her arrival the appropriate TMNT treatment by warning players to keep an eye on their pizza. Frankly, living with four pizza-obsessed mutant turtles probably means every slice is already under constant threat, so one more hungry resident shouldn’t make much difference. Most importantly, Pepperoni is included as part of The King’s Gambit rather than being separated into one of the paid DLC packs released alongside it.

Slash Joins TMNT: Splintered Fate as the Eighth Playable Hero

The King’s Gambit isn’t the only reason to begin another run. Slash has arrived through a separate paid character DLC, expanding the playable roster to eight heroes and bringing a considerably heavier approach to combat. Where some characters thrive on speed and mobility, Slash is built to feel like an enormous mutant turtle who can simply smash through whatever happens to be blocking the path. His huge claws, physical power and natural toughness make him a particularly imposing addition to the team. Slash can body slam enemies, roll through groups and use knockback effects to influence where opponents end up, giving players ways to control crowded encounters through brute force. He naturally works well with Water and Ooze powers, although those affinities aren’t meant to stop players from experimenting with different combinations. Slash must also be unlocked by defeating Leatherhead, so buying the DLC doesn’t immediately remove every obstacle between you and putting those claws to work.

Enraged Mode and Slash’s Abilities Create a Heavy-Hitting Playstyle

Slash’s signature Enraged mode gives his otherwise weighty fighting style an explosive burst of momentum. Activating the ability temporarily increases his movement speed while allowing him to inflict additional damage, turning an already powerful fighter into something enemies probably wish had stayed safely back in the Lair. The contrast is important because Slash isn’t designed around matching the natural speed of the quicker members of the roster. Instead, his normal strength and durability are supplemented by moments where Enraged mode lets him suddenly become much more aggressive. His DLC also includes five new Artifacts that can alter and strengthen different approaches to a run, providing more possibilities for players who enjoy experimenting with builds. Slash additionally has a unique Tool capable of calling down a meteoric explosion that inflicts heavy Dark damage on nearby enemies. Put everything together and he isn’t simply another character model with familiar attacks. His kit gives players a distinctly physical way to tear through Splintered Fate’s encounters.

Samurai Armor Gives Every Playable Character a Warrior-Inspired Look

Players who would rather change how the team looks than how it fights can turn to the separately available Samurai Armor Pack. The cosmetic collection gives the Turtles and their allies outfits inspired by traditional warrior imagery, with individual armor designs created to suit the personalities of the different playable characters. The pack supports Leonardo, Raphael, Michelangelo and Donatello alongside DLC characters the player has purchased, meaning an expanded roster doesn’t have to leave its newer members standing awkwardly in their normal clothes while everybody else looks ready for battle. Armor can be selected from the Character Select screen before beginning a run, keeping the cosmetic choice separate from the underlying progression and combat systems. That’s particularly useful for players who already have finely tuned builds and simply want a fresh visual style for another trip through New York. After dozens of runs, sometimes a new outfit is all the excuse you need to willingly walk into another room packed with Foot Clan ninjas.

The Platinum Bundle Brings the Released Add-Ons Together

Players joining Splintered Fate after its growing list of updates and DLC releases now have another option for collecting the available extras. The Platinum Bundle brings together the paid additions released so far, including Slash, Casey Jones & the Junkyard Jam, Metalhead, Alopex and the Samurai Armor sets, while also incorporating the free updates released for the game. That makes it particularly relevant to newcomers who haven’t gradually collected the individual additions as they arrived. The release also reflects just how much Splintered Fate has expanded beyond its original form. What began with the four brothers has steadily gained additional playable characters, challenges, story developments and other features, and version 2.0 now stands as the culmination of the main narrative arc. Super Evil Megacorp has described The King’s Gambit as a milestone rather than an endpoint for everything surrounding the game, with the studio indicating that further support will depend in part on continued player demand for more additions.

The King’s Gambit Gives Returning Players a Strong Reason to Start Another Run

One of the biggest challenges for any roguelike that receives long-term support is giving experienced players something meaningful to come back for. More cosmetic rewards are nice, and additional playable characters can refresh familiar encounters, but a proper endgame objective carries considerably more weight. The King’s Gambit tackles that problem by combining a story conclusion with a battle that specifically targets players who have already progressed through Splintered Fate’s major encounters. Rat King isn’t positioned as an alternate early-game route or a side activity that can be finished while learning the basics. He’s the destination at the end of everything the campaign has been building toward. That makes version 2.0 particularly interesting for players who previously defeated Shredder, rescued Splinter and felt they had seen most of what the main progression offered. Their established save now has another mountain to climb, and this particular mountain can apparently summon old bosses when it gets annoyed.

Version 2.0 Builds on Splintered Fate’s Expanding Playable Roster

Slash becoming the eighth playable hero also highlights how far the roster has moved beyond the original quartet. Leonardo, Donatello, Raphael and Michelangelo remain the heart of any TMNT adventure, but Splintered Fate’s additional fighters increasingly let players approach its repeated runs from different angles. Casey Jones, Metalhead and Alopex already broadened the selection before Slash entered the fight, and his emphasis on sheer physical force pushes that variety further. That’s especially valuable in a game designed around returning to familiar locations and encounters multiple times. A different character can change which powers feel useful, how aggressively you approach groups and which risks you’re comfortable taking. Slash’s Water and Ooze affinities, knockback options and Enraged mode create another combination to learn rather than simply providing more dialogue around an existing moveset. For anyone who enjoys finding a favorite hero and perfecting their approach, the roster now offers considerably more experimentation than the original lineup alone.

Nintendo Switch and Switch 2 Players Can Join the Fight

Nintendo players can experience Teenage Mutant Ninja Turtles: Splintered Fate on both Nintendo Switch and Nintendo Switch 2, making The King’s Gambit and the accompanying additions relevant across Nintendo’s current hardware generations. The game originally made its console debut on Nintendo Switch before later expanding to additional platforms and eventually Nintendo Switch 2. That wider availability has helped Splintered Fate grow well beyond its beginnings as an Apple Arcade release. For Nintendo players in particular, the game’s combination of fast combat, repeated runs and cooperative action has always been a natural match for a system that can move between handheld and television play. With The King’s Gambit now closing the main campaign, anyone who has been gradually progressing through the Switch version has a definitive final objective waiting beyond Shredder. Meanwhile, players arriving through Switch 2 can jump into a game that already carries years of additions rather than starting from the comparatively leaner launch version.

The Nintendo Switch 2 Legendary Edition Arrives on October 27, 2026

Splintered Fate also has another Nintendo Switch 2 release on the calendar. Super Evil Megacorp has reiterated that the retail Nintendo Switch 2 Legendary Edition is scheduled to launch on October 27, 2026, giving physical collectors another way to add the game to their shelves. The timing comes after version 2.0 and the arrival of Slash, putting the physical release in an interesting position as Splintered Fate reaches one of the biggest milestones in its post-launch history. For players who have intentionally held off for a retail Switch 2 edition, October therefore remains the date to watch. For everybody already playing digitally, however, there’s no need to wait before confronting Rat King or trying Slash. The King’s Gambit, the Slash character DLC and the Samurai Armor Pack have already been released, meaning the main story finale and the newest gameplay additions are available independently of the upcoming retail edition.

Conclusion

The King’s Gambit feels like an appropriate payoff for the main story Teenage Mutant Ninja Turtles: Splintered Fate has been building since its original release. Rat King provides the campaign with a genuine final challenge, complete with demanding unlock requirements, dangerous support from other bosses and a new ending waiting behind the victory. Pepperoni ensures the free update isn’t entirely devoted to making players suffer, while Slash gives those looking for another playable character a bruising new combat style built around strength, durability, knockback and bursts of Enraged aggression. The Samurai Armor Pack adds a visual alternative for the expanding roster, and the Platinum Bundle gives newer players a route toward collecting the paid additions released so far. Most importantly, version 2.0 doesn’t appear to represent Super Evil Megacorp simply shutting the sewer door and walking away. The developer has indicated that it intends to keep listening to players, leaving room for Splintered Fate to continue evolving after its central storyline reaches its conclusion.
