Mighty Action Heroes’ Move to Arbitrum: What Happened and Is It Still Playable?

Mighty Bear Games announced Mighty Action Heroes for Polygon, then planned a move to Arbitrum with Treasure. A 2025 shutdown report conflicts with a project page that still says open beta.

Mighty Bear Games first announced Mighty Action Heroes in 2022 as a Web3 battle royale planned for Polygon. In July 2023, GamesBeat reported that the studio would move the game to Arbitrum through a partnership with Treasure. That was a historical platform announcement, not a current launch notice: Games.gg later reported that the game went offline on July 22, 2025, while a project-linked page still labels it open beta. The available sources do not conclusively establish whether it can be played now.

What was Mighty Action Heroes?

Mighty Action Heroes was presented as a battle royale featuring action-movie-inspired heroes and digital items that players could own and trade. Mighty Bear Games described its approach as “games-first and fun-focused,” saying ownership and earning opportunities would be built into the game experience. That was the studio’s stated design goal, not a guarantee of earnings or resale value.

The project’s blockchain plan changed over time. The studio’s July 2022 announcement named Polygon. In July 2023, GamesBeat reported that Mighty Bear Games would shift the game to Arbitrum as part of a partnership with Treasure. GamesBeat quoted CEO Simon Davis saying Treasure’s ecosystem was built on Arbitrum and that the relationship between the network and ecosystem helped make the case for working with both. His comments explain the decision at the time; they should not be read as a current comparison of blockchain networks or confirmation that the game remains active.

How did access and the game change?

The early access path developed in stages. GamesBeat described an initial phase limited to holders of the Genesis Pass and Big Bear Syndicate NFTs, followed by an open beta intended to broaden access. The same report listed eight new heroes, item crafting, supply crates and tradable in-game items. It said players could log in with a wallet, while email login was still being developed. These were features and access details reported for that period, not a description of a currently operating build.

An earlier developer update described a browser-based early-access version and warned that its features and player-count plans differed from those envisioned for the full game. Later, Mighty Bear Games announced worldwide availability on iOS and Android. Those historical distribution announcements do not establish that the mobile apps or game servers still work.

Is Mighty Action Heroes still playable?

The available accounts conflict. Games.gg’s report, updated in November 2025, says the game shut down on July 22, 2025. However, the project-linked Linktree still describes it as “Available now in Open Beta” and links to mobile stores and other project resources. A link page can remain out of date, so that label alone is not evidence that the game is online. The sources reviewed do not provide a newer authoritative confirmation of its operating status.

What happened to the NFTs and other items?

According to Games.gg’s shutdown report, players could export NFT-based items to external wallets before services ended. The report says starter items were off-chain and could not be exported, and season passes were not refunded. These wind-down details come from secondary reporting; the available information here does not independently confirm them through a primary studio notice. It also does not establish whether any export option remains available now.
