Star Trek: Armada II is a real-time strategy video game published by Activision in 2001, based upon the Star Trek universe. The game was developed by Mad Doc Software. It is the sequel to Star Trek: Armada. Star Trek: Armada II was released by Activision a year after they acquired the full rights to all the franchise holding of the video game's franchise from Viacom. It was the first of the three major Star Trek video game sequel titles that were released by Activision from 2001 until their departure from the franchise in 2003. On December 13, 2021, both Armada and Armada II were re-released on GoG.com, which had also released several other older Star Trek titles earlier that year.

The Borg are an alien group that appear as recurring antagonists in the Star Trek fictional universe. The Borg are cybernetic organisms (cyborgs) linked in a hive mind called "The Collective." The Borg co-opt the technology and knowledge of other alien species to the Collective through the process of "assimilation": forcibly transforming individual beings into "drones" by injecting nanoprobes into their bodies and surgically augmenting them with cybernetic components. The Borg's ultimate goal is "achieving perfection."
