How to launch a web3 game on the Epic Games Store

We’re thrilled to announce that Flourish Islands, a delightful new web3 game built on Unreal Engine by Sequence, is now live on the Epic Games Store!

And it’s all made possible with the Sequence Unreal Engine SDK, the web3 toolkit designed for building seamless, wallet-enabled games on top-tier platforms.

How does Flourish Islands integrate web3?

Flourish Islands is a web3-enhanced city-building game where players collect resources, purchase items, and develop vibrant cities. They can leverage web3 assets to grow their territory, harvest materials like wood, and craft a personalized digital landscape.

Flourish Islands integrates blockchain through free on-chain minting of resource packs, allowing players to experience verifiable ownership without requiring cryptocurrency purchases or external wallets.

It uses Sequence’s Embedded Wallets, seamlessly generated from a player’s Epic Games account, and operates on the Arbitrum Sepolia proof-of-stake chain. Blockchain features are optional, with no in-app purchases or marketplace, ensuring the game remains accessible to all players regardless of their engagement with web3 elements.

With Flourish Islands now published on Epic, it proves what’s possible: web3 games can live alongside mainstream titles, accessible to millions of players. The game demonstrates a key point: blockchain features don’t have to be complex for players or developers. Sequence makes it simple to embed wallets, integrate on-chain assets, and build secure blockchain experiences, without friction.

Publishing a web3 game on Epic Games Store: What you need to know

Publishing a web3 game on Epic is not only possible, it’s straightforward with the right tools and understanding. Here's how we did it with Flourish Islands:

1. Enable blockchain disclosure

In your Offer > General Settings, toggle on "NFT and Blockchain". This flags your game as web3-enabled and adds a visible disclosure on your store page.

2. Create a compliant FAQ section

Epic requires an FAQ section with at least seven blockchain-related questions, addressing things like:

• What blockchain does the game use?
• Are NFTs involved?
• Is there a marketplace or trading system?

You can refer to Flourish Islands’ FAQ as a working example. Keep it transparent and player-friendly.

3. Prepare for review

The Epic review team may request:

• Details on how blockchain is used.
• A blockchain wallet for testing.

With Sequence, this is easy. You can explain that Embedded Wallets are non-custodial; you can’t create wallets for others. Instead, guide reviewers to create a wallet via your game’s sign-in (using Email OTP or Epic Auth).

4. Bonus tip: Keep it simple

If your game doesn’t include a marketplace or in-app purchases (like Flourish Islands), the approval process is significantly smoother. You can always add these features later after the initial launch.
