TOS Federation[ | ]

TOS Starfleet characters access a different version of the Beta Quadrant, one set in 2270, until they complete the mission “The Battle of Caleb IV”. This Beta Quadrant has a few different systems visible by default and focuses only on 9 sectors.

The graphic takes the design of maps seen in the 23rd century and shows the Romulan Neutral Zone. An attempt by the player to cross the Neutral Zone is stopped by the player's bridge officer, citing that they do not have permission to cross it.

DSC Federation[ | ]

DSC Starfleet characters access another different version of the Beta Quadrant, one set in 2256, until they complete the mission “Downfall”. This Beta Quadrant displays Starbase 1 and focuses only on 4 sectors.

The graphic resembles the war map seen in Lorca's ready room on the U.S.S. Discovery.
