A new faction, featuring Starfleet characters and stories set during the 23rd century, beginning in 2270.[1] Similar to the Romulan Republic, TOS characters will join the other factions for shared endgame content, following the Agents of Yesterday tutorial arc.[2] 23rd century missions will take place in a separated instance of sector space[2], and feature a 23rd century version of Earth Spacedock as a faction hub. Playable characters available to TOS faction are Andorian, Human, Tellarite and Vulcan.

New faction-agnostic missions include the Yesterday's War story arc:

Two new faction-agnostic missions were also added to the Future Proof story arc:

Temporal Operative Specialization[ | ]

Temporal Operative, a primary specialization that also introduces new Bridge officer abilities.[12] Bridge Officer abilities introduce a new game feature called Entropy, which is either applied or used when Temporal abilities are used on enemies.[13]

Temporal Defense Initiative Reputation[ | ]

A new Reputation for all factions.[1] The reputation includes two new space queues, “Days of Doom” and “The Battle of Procyon V”, and one new ground queue, “Miner Instabilities”. Temporal Marks will also be available from the Badlands Battlezone.[14]

Temporal Agent Recruitment[ | ]

An event, similar to the Delta Recruitment, in which new TOS characters will be able to earn special rewards. All characters created during the first six weeks following the expansion's launch are eligible to participate in the Temporal Agent Recruitment event.[15]

Confirmed voice actors and characters[ | ]

The expansion features the voice talents of Walter Koenig, Christopher Doohan,[1] Matt Winston, Vic Mignogna, Joseph Gatt, and Chase Masterson.[2] Spock also makes an appearance in the expansion, albeit with re-purposed lines from Leonard Nimoy's opening and sector block narrations.

Additional TOS characters[ | ]

Other characters from The Original Series appear without voice-acting and some have dialogue snippets from the Original Series, including Enterprise crew members Nyota Uhura, Hikaru Sulu, Mears, Leslie, Palmer and Hadley, as well as diplomats Sarek and Gav. James T. Kirk appears briefly in “Return to Babel”, albeit without dialog.

Kelvin Timeline[ | ]

Joseph Gatt portrays 0718, an augmented science officer from the U.S.S. Enterprise of the Kelvin Timeline, as depicted in Star Trek Into Darkness.[16] Lieutenant 0718 appears alongside other elements from that universe, including the re-imagined Constitution class and the Klingon D4 class. This is the first appearance of elements from the rebooted Star Trek movies in-game since the Red Matter Capacitor, which was available as a bonus item for special release editions of Star Trek Online in 2009.

Ships[ | ]

Agents of Yesterday features many new vessels, including Temporal vessels and era-appropriate, 23rd century ships.[1] The original Constitution class model has been rebuilt from scratch to fit the original studio model more closely.[17]

Several TOS-era vessels will receive T6 counterparts, which will be able to use the TOS-era skin.[18] Three new T6 vessels are available for Klingon and Romulan players[19], while the majority are available to Federation and TOS characters only.

Registry Numbers[ | ]

The newly released starships will be allowed to use era-appropriate registry numbers[20] (i.e., four-digit numbers for the Constitution, three-digit numbers for Daedalus class ships, and two-digit numbers for NX class ships).[21]

List of Ships[ | ]

Agents of Yesterday: Artifacts[ | ]

Agents of Yesterday: Artifacts was a mid-expansion update, released on October 25, 2016. It featured a new episode, “Echoes of Light”, introducing the New Frontiers, a story arc involving the Lukari.

Update included a new fleet holding (Fleet Station K-13), a revamp of the Kit system and updated lighting and graphics, as well as an introduction of a Sphere Builder Lock Box. In addition, New Romulus ground missions (including the New Romulus Reputation System missions) and Kobali Prime Adventure Zone missions were added to the mission journal.

Release History[ | ]

Agents of Yesterday was released on July 6, 2016. Similar to previous expansions, item packs are available for purchase, which contain several Zen Store ships, uniforms and other perks like titles and upgrade kits.[22]

Beta Testing for the expansion began in early May, with test builds being released on the Tribble test server. Since then, several updates have been released and new missions and systems were gradually released for testing.

Notes[ | ]

  • The expansion pays homage to the beginnings of Star Trek and can be seen as the game's contribution to the 50th anniversary celebrations of the franchise.
  • The development team was adamant about maintaining the art style of The Original Series, including limiting the character selection to only the original four Federation species (Human, Andorian, Tellarite, and Vulcan), adding props and maps with a unique 60s feel and adding a grain filter on most 23rd century maps. The grain filter is available on all 23rd Century ships as a toggle button to the left of the turbo-lift facing the viewscreen.
