Artifact (Spartan Ops)/Gagarin

Gagarin is the fifth chapter of Spartan Ops ' second episode, Artifact.

Summary
Fireteam Crimson arrive to a research station within a large Forerunner structure where Science Team Gagarin was last located. Gagarin, who have since gone missing, is no where to be found. The place is seemingly abandoned when no one is detected, leaving Commander Palmer skeptical of the situation. Spartan Jared Miller points to the back end of the station where Gagarin was last known to be. Crimson investigates and are told by Palmer to access an audio log from a nearby computer. Upon accessing the log, they hear the scientists activating an unknown object without caution. Miller is then told by Infinity Science to investigate two nearby consoles Gagarin had activated. Palmer, realizing the danger of the situation, orders Crimson to shut it down. Upon deactivating the first console, Promethean Crawlers and Knights translocate near them. After eliminating the first few Prometheans and deactivating the second console, Miller detects more activity within the structure. More Prometheans show up and engages Crimson.

As Crimson fights to clear the area of hostiles, Miller points to several computer consoles that gradually reveal Gagarin team's fate as well as more Forerunner devices that had been activated. This eventually leads to four power sources of a large Forerunner artifact that had been activated by Gagarin team. Palmer orders Crimson to shut it all down. After doing so, Crimson clears out the remaining Prometheans before being extracted. As UNSC Marines are sent in to hold the structure, Miller hypothesizes that whatever happened to Dr. Glassman could have happened to Gagarin team.
