Event

In Arknights, events, officially known as limited-time events, act as content releases that further expands Arknights' gameplay and/or setting by introducing new content from operations to Operators, enemies, and coverage of subjects that are not elaborated in the Main Theme (although not always). Events also act as temporary instances where players can claim various rewards through gameplay progressions.

List

All events are assumed to start on 04:00 or 10:00 UTC-7 and end on 04:00 UTC-7 in the Global server.

Overview

Based on the scale, events can be divided into major events, minor events, commemorative events, seasonal events, special events, and crossovers.

Major

Major events feature their own operations and stories/interludes, and are distinct in that they tend to feature much more robust event stores, and introduce new "tilesets" with some exceptions (notably Operation Originium Dust and A Walk in the Dust which reuses an identical tileset) as well as new enemies and mechanics. The stories/interludes of major events are always unlocked in sequence, and is tied to the operations themselves; the major event's plot are usually contained within the main operations, though some are also included in the extra operations.

All major events will receive a rerun (known in the CN server as retrospection) at a later date following the event's release.

As of A Walk in the Dust, major events are grouped into two categories and their operations become available to play permanently after release, with some restrictions (see Event operations § Major).

• Intermezzi
• Side Stories

Minor

• Story Collections
• Login events: These events can be run during or separate from any other event, as they are "non-intrusive." The systems of login events differ from one another, but they are usually defined by giving out rewards for logging in several days in a row, or add temporary additional rewards to daily and weekly missions. The rewards for these events are typically simple materials and an outfit.

Commemorative

Commemorative events are released to celebrate the release of Main Theme episodes or other important dates. Commemorative events usually grants access to all Supply operations, like that of Contingency Contract, and often includes login events. They also give all operations that costs Sanity with the exception to Annihilation a special drop in form of Emergency Sanity Sampler or a box that contains various upgrade materials. The specific mechanics of commemorative events are subject to change on a per-event basis.

Three types of commemorative events always include a limited headhunting banner, but have different release dates across the Arknights servers due to differing content release schedules (see Trivia).

• Celebration: There are two different Celebration events.
  1. In CN, first Celebration events are released in November 1 to commemorate half-year anniversaries; in Global, they are released in late April or early May (which usually coincides with the Golden Week in Japan) to act as an interim between the Carnival and Festival events, and labeled Thank-You Celebration.
  2. In CN, second Celebration events are released in May 1 to commemorate yearly anniversaries; in Global, they are released in late October or early November (which is close to Halloween) to act as an interim between the Festival and Carnival events.
• Festival: In CN, Festival events are released in late January to early February to commemorate the Chinese New Year; in Global, they are released in late July or early August to commemorate half-year anniversaries.
• Carnival: In CN, Festival events are released in August 1 to to celebrate the peak of Summer; in Global, they are released around January 16 (Global's release date) to commemorate yearly anniversaries.

Trivia

• Due to being 8–9 months behind the CN server at launch and ~6 months behind at present, the Global server of Arknights released events — those featuring limited headhunting banners in particular — outside their supposed theme by necessity. At first the TW server also had this distinction, but since Here A People Sows events are released in TW closely matching their theme.
  • In CN, Celebration events are intended to commemorate anniversaries while Festival and Carnival events are intended to commemorate Chinese New Year and summer, respectively; Global instead releases both Celebration events as an "interim" between the Festival and Carnival events which are released to commemorate Global's half-year and yearly anniversaries, respectively.
    • This is because since the 1st Anniversary Celebration, Global's content release pacing allows CN's Summer and Chinese New Year events to be released as Global's yearly and half-year anniversaries, respectively, and CN's anniversary events to be released in between them on Global, as explained above.
    • As a consequence, Global reschedules the release of at least one event preceding Carnival events from Dossoles Holiday into February or March to make way for the Carnival event as Global's yearly anniversary event.
  • Interestingly, the above caused Global to release the summer-themed Carnival events in January, whilst the Northern Hemisphere is in winter which makes the event totally out-of-season. This is not the case for the Southern Hemisphere (especially equatorial countries) however, which is in dry/hot season on January.
    • Possibly because of this fact, Carnival events since Adventure That Cannot Wait for the Sun (and to a lesser degree, So Long, Adele) no longer emphasize too much on summer elements so that it won't be out of place for some Global players by the time the event is released in Global. An arguably similar situation is also the case for Festival events, which do not emphasize on Chinese New Year elements since Who is Real because Global releases them while the Northern Hemisphere is in summer.
  • Chronologically Global's half-year anniversary falls on July 17, but Global celebrated half-year anniversaries by releasing Festival events in late July/early August so it would coincide with the release of Carnival events in CN. This is also the case with Celebration events, which are released in Global to coincide with their CN release.
    • As the result, the Global release of second Celebration and Carnival events is 2.5 months apart, while the release of Carnival and first Celebration events is 3.5 months apart; unlike the release of events featuring limited banners in CN which is consistently 3 months apart.
  • There are three instances where Global does not follow this release pattern:
    • Darknights Memoir, which was supposedly released in late October/early November 2020 if going by the CN order, is released much later, in early December 2020 just before the 1st Anniversary Celebration because the limited banner pattern is not formalized during this time and it would have been too soon after the Half Year Anniversary (specifically Ancient Forge), forcing Global to reschedule the release of Children of Ursus, Twilight of Wolumonde, Contingency Contract Pyrite, and Grani and the Knights' Treasure Rerun that succeeds DM in CN to precede it in Global.
    • Il Siracusano is released in late May 2023; almost one month later than intended, with Snow Upon Autumnal Winds Login Event filling the gap between Episode 11: Return to Mist and IS.
• There is usually a downtime of up to 7 days between event releases (coloquially known as "dead days" or a "dead week") in Global. However, consecutive/back-to-back event releases do occur in Global at times, usually if the succeeding event does not feature new Operators from headhunting.
  • If there are more than 7 days of downtime, Global would held a minor, non-intrusive event covering said downtime.
• While CN sometimes have two events overlapping with each other, such never happens in Global (outside of non-intrusive events such as login ones and Trials for Navigator seasons) until Pinch-Out Experimental Operation, which overlaps with the last few days of Stultifera Navis Rerun.
• It is worth noting that event operations are typically designed to the advantage of the Operators introduced by the headhunting banner that runs concurrently with the event. For example, Passenger's ability to chain arts damage to close-by targets would be advantageous against A Walk in the Dust's various drone summoners, as would Heavyrain's ability to heal and provide Camouflage.
