Question 1

Do I need to own Final Fantasy XI?

Accepted Answer

No. The HorizonXI launcher downloads a complete game client itself. No retail purchase, no Square Enix account and no monthly subscription.

Question 2

What content is available?

Accepted Answer

Everything up to and including Treasures of Aht Urhgan, at a permanent level 75 cap, matching a retail patch date of 17 April 2006. Later expansions are planned but will be rebalanced into level-75 content rather than raising the cap.

Question 3

Can I dual-box or play alongside someone in my house?

Accepted Answer

Not by default — one account per IP address and three characters. Shared households and LAN parties request an IP exception in the HorizonXI Discord, which needs filing in advance.

Question 4

Which add-ons are allowed?

Accepted Answer

HorizonXI publishes explicit approved and prohibited lists on its add-ons page, and anything not on the allowed list is not permitted. The launcher can enable approved ones for you. Submit a Discord ticket to have a new one reviewed.
