The Hogwarts Legacy community has received an unexpected gift in the form of ‘The Flooded Laboratory,’ a substantial new quest mod that breathes fresh life into the beloved wizarding RPG. Created by modder MTL_LD, this free addition comes at a perfect time for fans disappointed by Warner Bros.’ cancellation of official DLC plans.
The mod transports players to a previously unexplored coastal area near Cragcroft, where mysterious tremors and missing Ministry officials hint at dark magic lurking beneath the surface. With the game’s sequel likely years away, this high-quality fan creation offers a compelling reason for PC players to dust off their wands and return to the magical world they fell in love with.

Uncovering the Secrets of the Flooded Ruins
‘The Flooded Laboratory‘ expands Hogwarts Legacy‘s world with carefully crafted new content that feels surprisingly authentic to the original experience. Players begin their investigation by traveling to the southeastern cliffs of Cragcroft, where they’ll discover a hidden cave entrance leading to the titular flooded ruins. The mod introduces several engaging gameplay elements, including environmental puzzles that require magical problem-solving, tense encounters with goblins that only appear after nightfall, and subtle storytelling through scattered clues and documents.
What makes this mod particularly impressive is how seamlessly it integrates with the base game’s systems while offering a self-contained adventure that lasts roughly 1-2 hours, providing just enough new content to feel substantial without overstaying its welcome.
The Perfect Antidote to Post-Game Content Drought
This mod arrives at a critical moment for Hogwarts Legacy’s dedicated fanbase. After completing the massive 50+ hour campaign and all side activities, many players found themselves craving more reasons to return to the wizarding world. The cancellation of planned DLC left this desire unfulfilled until now. ‘The Flooded Laboratory’ successfully captures the magic of discovery that made the base game so special, offering fresh environments to explore and mysteries to solve.
The mod’s popularity is evident in its rapid accumulation of over 7,500 downloads shortly after release, proving there’s still strong demand for new Hogwarts Legacy content. While not an official addition, the care and attention to detail evident in this mod demonstrate how passionate fans can keep a game alive long after developer support ends.
Simple Installation for Immediate Adventure
Getting started with ‘The Flooded Laboratory’ couldn’t be easier for PC players. The modest 60MB download from CurseForge installs quickly through popular mod managers, requiring no complicated setup or technical knowledge. Once installed, the new content integrates naturally into the existing game world, with the quest triggering automatically when players approach the designated coastal area near Cragcroft.
The mod maintains all of the player’s existing progress, spells, and equipment, ensuring a seamless transition from the base game to this new adventure. While console players unfortunately can’t access this content due to platform restrictions, the mod represents another compelling reason for Harry Potter fans to consider the PC version’s superior modding potential.

While Warner Bros. may have moved on from official support, the active modding scene ensures the wizarding world will continue to grow and evolve. For players who’ve completed everything the base game offers, this mod – and likely others to follow – provides the perfect excuse to return to Hogwarts and experience the magic anew.
