To view your NFTs in the game, make sure you connect the right wallet (the wallet that has your NFTs) to your game account.  If your NFT is not in your primary wallet, you can connect your secondary wallet to the game account on the website as shown and your NFTs should show up in the game! :)

Please note that the passport wallet is the default wallet linked to your game account. And it is the native wallet for Immutable zkEVM blockchain where Genesis Commanders are minted. You will have a more smooth user experience with Passport wallet to hold and trade your Genesis commander NFTs.
