Star Trek Ascendancy
Unofficial Complete Rulebook


What is the UCR?

The UCR (Unofficial Complete Rulebook) is a mod for Star Trek Ascendancy.

The UCR was initially concieved as a improved rulebook, incorporating FAQ answers, resolving ambiguities, and adding reference numbers. Over time, it has grown to include several fan faction expansions, including Bajoran Republic, Gorn Hegemony, Terran Empire, Orion Syndicate, Tholian Assembly, and Dominion factions, as well as a completely redesigned Vulcan faction.

The latest version, UCR4, includes versions of all official factions released to date, including the new ones from the Final Frontier expansion. Some factions are very different, but they're all here. Some official modes and variants, such as the Dominion War, are not supported.

Version History

UCR1.0 was published in 2018. The initial version includes the Ferengi, Cardassian, and Borg expansions.

UCR 1.1 through 1.4 improved the Borg rules and the layout of the rulebook, and incorporated some new FAQ answers.

UCR 2.0 incorporated the Andorian Empire and Vulcan High Command expansions and added two new factions: the Terran Empire and the Orion Syndicate.

UCR 3.0 added two new factions: the Tholian Assembly and the Dominion. It also added 40 new system disks, updated cards for many official factions, and made some rules changes.

UCR 4.0 added two brand-new factions: the Bajoran Republic, and the Gorn Hegemony. It also added support for the official Breen faction, and a fully-redesigned Vulcan faction. The Vulcans, Bajorans, Dominion, and Orions all utilize new rules for Agents, stealthy ground units that move from planet to planet.

More detailed version history can be found at the end of the Appendices.

Future History?!

UCR5.0 is a work in progress. The focus will be on reworking more of the official factions into new, more exciting variants. We will also be making necessary changes to make sure that those with the Final Frontier version of the base game can still enjoy the UCR. Other factions that may be on the horizon include Tellarites, Bolians, and Betazoids.

Cut Content

The official Dominion War mode is not technically supported by the UCR. Playing this mode with UCR factions and rules should work fine, but we have not written UCR-style rules it, nor have we provided new cards with UCR-style wording. At present, there is no intention to do so. It is likely that some of the Final Frontier modes will end up like this as well in future versions.
