Astro Arena does not require a separate sign-up process — you can start playing immediately with a guest login. However, guest account data is stored only on your local device, so your gameplay progress may be lost if you change devices. We recommend converting your guest account into a registered account by linking one of the following:

Supported Linked Accounts:

• KRAFTON ID (KID)
• Google Account
• Apple Account

However, on AOS devices with less than 4GB of RAM, the Apple account login option is not displayed due to the risk of crashes.
