Giantess Playground is a city-destruction sandbox where you either tower over a metropolis as a giant woman and flatten skyscrapers, or scramble through the streets as a tiny citizen trying to survive. Built in Unreal Engine 5, it has quietly moved from a Patreon-funded passion project into a paid early access title. Now the game is at the center of an ownership fight, with its original creator saying the Steam version went live without permission.
Quick answer: The dispute is between the game’s original developer, who goes by GiantessGameUE5, and publisher Aggressive Mastery Inc (run by Micah Berninghausen, known online as GameDevMicah). Both sides claim to own or control the game. GiantessGameUE5 says the August 14, 2026 Steam launch was unauthorized and is gathering evidence for legal action, while Aggressive Mastery disputes the creator’s account.
What Giantess Playground actually is
The game is a destruction sandbox with several modes and a roster of more than 20 characters. You can view the action from first person, third person, or even a ground-level angle looking up at the giant. It supports Japanese voice work and multiple text languages, and it runs on the same Megacity environment Unreal Engine 5 ships as a demo, which is why the destruction looks detailed from the start.
| Mode | What you do |
|---|---|
| Sandbox | Resize the giant from tens to hundreds of meters and destroy the city with no time limit or spawn limits. |
| Rampage | Start around 40 meters tall, grow as you destroy, and try to crush as much as possible before time runs out. |
| Hide and Seek | Play as a citizen and avoid capture, with a short head start before the giant begins moving. |
| Commander | Act as a citizen and direct the giant toward targets to destroy. |
It carries a Mature 17+ rating for blood, suggestive themes, and violence. The Epic Games Store early access version is priced at $19.99.
How the dispute unfolded
The game began as a solo effort. GiantessGameUE5 first shared it in 2022 through a Patreon page, funding development with supporter contributions and posting frequent updates. The partnership with Aggressive Mastery came later, and the split appears to trace back to a disagreement over how fast to release the game and how to make money from it.
| When | What happened |
|---|---|
| 2022 | GiantessGameUE5 releases the game to Patreon supporters. |
| January 2025 | Collaboration with Aggressive Mastery begins; Micah Berninghausen’s destruction plugin and visual effects are integrated. |
| July 2025 | Aggressive Mastery publishes the game in early access on the Epic Games Store, an event both parties announced at the time. |
| June 2026 | The two clash over release plans and revenue; GiantessGameUE5 moves to end the collaboration. |
| August 12, 2026 | GiantessGameUE5 posts that the other party controls the storefronts without authorization and is keeping the revenue. |
| August 14, 2026 | Giantess Playground goes live on Steam; the creator calls it unauthorized. |
The creator’s claims
GiantessGameUE5 describes the arrangement as informal. By their account, they remained the owner and copyright holder while Micah would earn a share of Epic and Steam revenue in exchange for helping with development and sharing costs. For a while it worked, the destruction plugin was added, and the project drew more support.
The relationship broke down over direction. The creator says they wanted to keep polishing the game into something with real gameplay and replay value, while Aggressive Mastery pushed to maximize revenue by moving into early access and adding paid extras. They say the two argued over this on several voice calls. Eventually GiantessGameUE5 handed the game over, left the revenue to their collaborator, and asked for one thing in return: no Steam release.
That request is now the core of the fight. The creator says they were removed from the Steam and Epic developer accounts, cannot push updates or provide support, and never approved a Steam launch in the game’s unfinished state.
Aggressive Mastery’s side
Aggressive Mastery is listed as both developer and publisher on the Epic storefront. The publisher makes an ownership claim of its own, and the two sides have traded accusations that each cut the other out of development. Micah Berninghausen has directly pushed back on the claim that he refused to negotiate.
The Epic listing also carries a detailed disclaimer stating that Aggressive Mastery LLC takes no responsibility for user-created content, prohibits distributing modified versions of the game, and reserves the right to act legally to protect its interests.
Where things stand for buyers
Giantess Playground is currently in early access on both the Epic Games Store and Steam, alongside the Patreon build. Because the ownership question is unresolved, the future of updates and support is uncertain. The original developer says they cannot maintain the Steam or Epic versions, so the person who built most of the game may not be the one patching it.
The underlying agreement seems to have rested on little more than a handshake, with each party claiming the title as their own. That makes a quick resolution unlikely, and it means anyone buying in now is stepping into a game whose ownership and continued development are both actively contested.
