Odencat is giving Meg’s Monster fans one more reason to revisit the underworld. The studio has confirmed that Meg’s Monster: Lost Memories, the first story DLC for the 2023 tearjerker RPG, will launch on December 4 for Nintendo Switch, Xbox One, Xbox Series X|S, and PC via Steam.

Digital pre-orders are live now on the Nintendo eShop and Microsoft Store with a 10% launch discount, while the base game is currently 40% off on Switch until December 3.
Lost Memories isn’t entirely new content. The DLC originally debuted earlier this year in Japan as part of a physical Switch edition that bundled the base game with an extra story episode and a small pile of collectibles.
That release gave local players early access to roughly 90 to 120 minutes of additional narrative focusing on the monsters’ past lives, along with an in-game tablet that lets you browse artwork and materials as you progress. The December 4 launch finally turns that content into a standalone digital add-on for players worldwide.

Meg’s Monster: Lost Memories is described as a collection of short prequel adventures built to expand the world and lore of Meg’s Monster. It strings together five self-contained stories, each centered on a different character whose life intersects with the underworld.
There’s an MMA fighter climbing into the ring again and again to pay for his brother’s medical treatment, a little girl caught between parents who act increasingly tense as her fifth birthday approaches, and a formless creature shut away in a cell, bred solely to assassinate a specific human target.
The last two tales focus on a man who dies and wakes up as a monster, then dedicates his new existence to bringing order to the underworld, and a monster child raised in a lab, pushed through cruel experiments for reasons that only become clear at the end.

Taken together, these five vignettes are meant to circle back to the same questions that sat under the original game: what actually makes someone human, and how easy is it for a “normal” person to act more monstrous than the creatures we usually call monsters?
Odencat pitches Lost Memories as a compact, roughly two-hour story pack that leans harder into drama and tragedy than the main adventure. Developer Ryota notes that the team aimed for a “considerably more serious” tone this time and even built a detailed timeline of events in the underworld to make sure each backstory slots cleanly into canon.
For anyone who missed it the first time around, Meg’s Monster itself is a short, story-driven JRPG about Roy, a hulking ogre who stumbles across a lost human child named Meg in a realm where humans are usually on the menu.

The gameplay revolves around Meg crying. If this happens, the sky turns red, and the world starts to end, so Roy’s 99,999 HP doesn’t matter nearly as much as keeping her calm. Combat plays out in turn-based encounters where Roy is functionally unkillable, but Meg’s emotional state becomes the real health bar you’re watching, using toys and small interactions mid-battle to reassure her while you deal with enemies.
That was the original idea that helped the game stand out when it launched on Xbox One, Nintendo Switch, and PC in March 2023, and it’s built a reputation as one of the more emotional indie RPGs of the last few years.
Steam players have given Meg’s Monster an “Overwhelmingly Positive” rating, with around 96% of more than a thousand reviews marked positive. Critically, it has been praised for its writing and soundtrack: Nintendo Life called it a “one-of-a-kind adventure with a lot of heart,” while LadiesGamers highlighted how strongly it “tickled [their] heartstrings.”

IGN Japan singled out the well-paced twists and piano-driven score, and Korean outlet Inven pointed to the emotional soundtrack and tight, compact storytelling as the main reasons it hits so hard.
On Xbox, Meg’s Monster: Lost Memories is listed at $4.99 as an add-on that works with the existing Xbox One and Xbox Series X|S versions. On Switch, the DLC is also set at $4.99 in North America, with a pre-order price of $4.49 thanks to the 10% discount that runs through launch week. In all cases, you’ll need the base game to play.
The Switch eShop discount cuts the base game price by 40% until December 3, and you can stack that with the DLC’s 10% off pre-order to pick up the whole story for the price of a typical indie RPG. With an estimated two hours of extra material, Lost Memories looks like a focused epilogue-style return to a world that was already designed to be played in short sessions.
