The English version of the free-to-play mobile RPG Fate/Grand Order is running a campaign that lets you choose one 5-star Servant, the highest rarity (also called SSR). The campaign marks the game reaching 100 million downloads worldwide, and the English version’s official site says the campaign is running simultaneously on all servers. Every deadline is in Pacific time (PT), and the 5-star exchange closes at 6:59 a.m. PT on December 14, which is 9:59 a.m. ET.

The 100 million figure includes versions outside Japan. Fate/Grand Order launched in Japan in July 2015. TYPE-MOON’s Kinoko Nasu is its general director, among other roles. As you move through the main story, you strengthen your Servants and raise their Bond. The English version is listed on the US App Store and Google Play as “Fate/Grand Order (English).”

The centerpiece of the “100 Million Downloads Worldwide Celebration Campaign” is the 5-star Servant exchange, with 43 Servants to choose from. You get the ticket by clearing Section 1 of First Singularity: Hundred Years’ War of the Evil Dragons, Orleans, which comes early in the main story, so even brand-new players can reach it. Tickets are handed out until 6:59 a.m. PT on November 30, and the exchange itself happens at the Da Vinci Workshop.

The exchanged Servant isn’t yours for good yet. Raise it to Lv. 60 and Bond Lv. 5 by 6:59 a.m. PT on December 31 to make it a permanent part of your roster.

Limited missions award a Craft Essence for the 100-million-download milestone. Finish all of them and you collect 30 Saint Quartz in total, which the official page says is worth up to 11 Saint Quartz Summons. The missions also end at 6:59 a.m. PT on November 30. A frame and stickers for the #FGO100MDL hashtag on X are available until 7:59 p.m. PT on November 20 (10:59 p.m. ET).

There are three deadlines: the ticket deadline at the end of November, the exchange deadline in mid-December, and the deadline for the Servant to become a permanent member at the end of December. Picking a Servant first and spending the rest of the year raising it looks like a practical approach.
