Description

Contingency Contract: Indigo Experimental Operation is the second test season of the Contingency Contract mode, opening November 5, 2026 at 12:00 server time. Gryphline’s Version 1.6 update notes run it until the next version update without dating that update, with a content update on November 12.

Event missions pay a Silverblade Medal portrait, a Contingency Respondent portrait frame and Vitrified Indigo. The Vitrified Indigo is spent at the Secret Sanctuary, which stays open until December 3, 2026 at 04:00 server time and stocks 2,000 Oroberyl, a "Contingency Resolved" sticker and Advanced Progression Selection Crate II.

Neither the update notes nor the wiki list the Test Criteria themselves yet.

How this page is maintainedContingency Contract: Indigo Experimental Operation’s dates, type and rewards come from endfield.wiki.gg and, for the current and upcoming slate, Game8’s Arknights: Endfield events archive. Nothing is invented to fill a gap. This page was checked against both on Oct 17, 2026; where a source has not published a detail yet (an end date, an exact reward count), the page says so rather than guessing.
