The latest patch brought a host of new adventures with it, so Square Enix is offering up to 96 hours of free playtime.
Patch 3.2 updated Eorzea with an array of new adventures, and to entice players who have fallen by the wayside and abandoned their subscriptions, Square Enix are looking to entice them back, with four free days of roaming the realm.
The campaign schedule runs from Monday March 14 at 12am PDT, to Wednesday April 13, at 11.59 pm PDT. Your four free days will kick off as soon as you log in during this period, but they won't run over the end of the campaign date, so if you log in on April 11 for example, you can't play beyond April 13.
To be eligible, you must have already purchased the game, and have an account which has been inactive for at least 30 days.
You can read up on all of the particulars over at The Lodestone.
