03 / GOOD TO KNOW
Before you launch.
Do I need to own Minecraft?
Yes. You need Minecraft Java Edition and a Microsoft account that owns it. Echo does not include or sell Minecraft.
Can I use other mods?
Compatible Fabric client mods and resource packs can be added to the Echo profile. Compatibility with every third-party mod is not guaranteed.
What happens when I cancel?
Cancellation stops future renewals. Access remains until the paid period ends. At expiration, Echo cannot be activated and a Minecraft session with a verified Echo subscription is closed. Save your world before the end time shown in your account.
Does Echo work on every server?
Echo is designed for Sword PvP on compatible Minecraft Java servers that allow automation. Support depends on server versions, plugins and rules, so check compatibility before playing.
Can I use it offline?
An internet connection is required. Short-lived access checks control Echo access. After linking, loss of verification closes Minecraft within two minutes. Link your account again after restarting the game.
