Star Trek: Legacy is a 2006 real-time tactics space combat video game for Microsoft Windows and Xbox 360 developed by Mad Doc Software and published by Bethesda Softworks in association with CBS Paramount Television and CBS Consumer Products. Players control a fleet of various Federation starships (up to four) through four different Star Trek eras in combat.

Originally slated for release in the fall of 2006 to coincide with the 40th anniversary of Star Trek, the Windows version was not released in North America until December 5, 2006, and the Xbox 360 version until December 15. In Europe, both the PC version and the Xbox 360 version were released on December 22, 2006.

The game represents the first time that the five actors who portrayed each of the captains in the five individual Star Trek shows up until that time, William Shatner, Patrick Stewart, Avery Brooks, Kate Mulgrew, and Scott Bakula had participated in the same project. The PC version of the game was met with mainly negative reviews, whilst the Xbox 360 version fared slightly better with critics.

Gameplay

Players control a squadron of one to four 3D modeled starships, and engage in battles against other starships. Starship movement is controlled with pitch, yaw, and forward propulsion (as well as a straight-line "warp" capability for rapid movement across a map). Movement occurs in a fully 3D "pizza box" shaped environment. The player operates a single starship at a time, controlling weapons fire, movement and repairs, and can switch between each of the starships in their squadron. Players also have the ability to change from a 3D display to a top-down 2D tactical display where they can issue specific commands to ships within a task force; for example, the player is able to order a ship to warp to a specific point on the map.

Viewpoint is controlled in several ways, with players able to "lock" onto an opponent to ensure that the opponent is always centered in the screen, to look straight forward, or to rotate camera around the selected ship. Starships are classified according to weapons strength and maneuverability, and assigned a set number of points that roughly corresponds to the strength of the ship. The player earns "command points" during each mission, and can select new ships to add to their squadron by spending these points between missions.

In addition to the linear campaign, there is a customizable skirmish mode. Players select the map on which to play, the number of ships per squadron, the number of command points allowed, the race and allegiance of each AI player, and the make-up of their own squadron. In skirmish mode, players are not limited to controlling Starfleet vessels as they are in the campaign; they can control the ships of the different races faced in the campaign, namely the Borg, the Klingons, the Romulans, the Dominion, as well as other assorted factions and ship types. A mode of play included in later versions of the game is the "coop wave" mode, in which a player (with up to 6 other "squadrons/fleets") guards a station from assault by increasingly harder-to-defeat enemy fleets, increasing in gradual waves. Bethesda has also released a mission editor tool allowing users to freely customize missions.

The PC version of the game has several modification tools. One such mod is the "Ultimate Universe Mod", which allows players to utilize a mass armada (with both sides' ships chosen out of a list of 450+ starships across all races), or battle with pre-determined ships for both sides. Ultimate Universe adds a new mode called "Historical Battles", in which players may fight famous battles from the Star Trek series, from multiple points of view.

Storyline The single-player campaign spans the three eras of Star Trek: Enterprise (ENT), The Original Series (TOS) and The Next Generation (TNG). The Original Series era also includes elements from the Original Series films. The Next Generation era includes elements from Deep Space Nine (DS9), Voyager, (VOY) and the Next Generation films. In each era, the player utilizes a fleet of Federation ships from that era to combat the Romulans (ENT), Klingons (TOS), and Borg (TNG).

The eras covered in single-player, with the corresponding captains and main ships, are:

Jonathan Archer (Enterprise (NX-01) - ENT) James T. Kirk (USS Enterprise - TOS, The Motion Picture, The Wrath of Khan and The Search for Spock) (USS Enterprise-A - The Voyage Home, The Final Frontier and The Undiscovered Country) Jean-Luc Picard (USS Stargazer - TNG) (USS Enterprise-D - TNG and Generations) (USS Enterprise-E - First Contact, Insurrection and Nemesis) Benjamin Sisko (USS Defiant - DS9) Kathryn Janeway (USS Voyager - VOY)

Enterprise Era The story begins in 2159, approximately four years after the events of "Demons" and "Terra Prime" and two years before the decommissioning of Enterprise (NX-01) in 2161 (see "These Are the Voyages...") as Captain Jonathan Archer (voiced by Scott Bakula) is sent to search for a missing Vulcan science ship in a nearby star system. Enterprise arrives but is immediately attacked by Romulans. After fighting off the Romulans, Enterprise finds the Vulcan ship under attack from another group of Romulans. After saving the ship, the Seleya, their captain, Commander T'Uerell (Bari Biern), asks Enterprise to accompany her to her research station, Gravenor, which, she fears, may also be under attack. Upon reaching the station, T'Uerell's fears are proven correct, as Romulans are attacking the station. T'Uerell docks to evacuate her people while Enterprise holds off the incoming Romulans. However, T'Uerell breaks off radio contact and disembarks from the station seconds before the Gravenor explodes, with a full crew complement still on board. As T'Uerell departs, she thanks Archer for defending her whilst she recovered her protomatter from the station. She flees, and the badly damaged Enterprise is forced to return to Earth.

Some time later, Enterprise is ordered to escort three medical ships through a system where a viral epidemic has broken out. Several times the Romulans attack, but each time, they are repulsed. The medical ships are able to deliver the antidote, and the epidemic is cured. However, it is confirmed that the virus was artificially created and released into the planets' ecosystem on purpose. Enterprise is sent to discover where the virus came from. After identifying the design of a vessel seen navigating through the system just prior to the outbreak, Enterprise proceeds to a nearby planet. Upon arrival, however, they find the virus has been released on the planet, and all life has been wiped out. They search through the system, finding several ships harvesting the virus from gas giants and several harvesting stations orbiting nearby planets in preparation to release the virus into the atmosphere. They destroy the stations, but one harvesting ship is able to escape with a sample of the virus.

Enterprise then learns that the Romulans are mounting a large-scale attack near Earth, and they arrive just in time to prevent the destruction of a starbase. They learn that the ship with the virus has had its contents distributed to three smaller ships, and these three ships are now being escorted towards Earth by the Romulan fleet. Using nearby mining facilities, which still use nuclear fusion, Enterprise is able to disable the engines of the three ships, which the starbase subsequently destroys. With this, the remaining Romulan ships disengage and Earth is saved.

Original Series Era The game then cuts to 2270, the era of the original Constitution-class USS Enterprise (NCC-1701) under the command of James T. Kirk (William Shatner). It is the height of a war with the Klingon Empire, and Starfleet Intelligence has uncovered the development of an advanced Klingon weapons platform. Kirk is tasked with stealing an experimental Klingon Bird-of-Prey which has been fitted with a prototype cloaking device. After successfully doing so, Kirk pilots the vessel to the weapon platform. While under cloak, Kirk sees the Seleya at a mining facility, and listens in on a conversation that reveals T'Uerell designed the weapons platform in exchange for mineral deposits. With this information in hand, Kirk recommends that Starfleet conduct an immediate strike on the platform. Kirk is assigned a task force and destroys the weapons platform, where he again encounters T'Uerell, who warps out of the system.

Twenty years later, T'Uerell appears at a classified Federation research station. Now in command of the new Constitution-class USS Enterprise (NCC-1701-A), Admiral Kirk avoids going into retirement so as to deal with the matter. Kirk is able to regain control of the station after a skirmish with some Klingon vessels. Upon beaming an away team aboard, they report the presence of mysterious cybernetic implants in what used to be the Klingons aboard the station. Kirk confronts T'Uerell, who again flees, leaving behind a large Borg sphere and three mysterious orbs. By destroying the three smaller spheres, Kirk is able to destroy the main sphere. However, upon the sphere's destruction, a massive explosion destroys subspace for a three light-year radius. As he contemplates his failure to capture T'Uerell, Kirk states, "Hopefully the next generation will do better."

Next Generation Era The game then cuts to 2333 as the USS Stargazer monitors several Romulan vessels engaged in combat with T'Uerell in a nearby star system. The Romulans are destroyed when T'Uerell uses a super-weapon on a planet in the system, instantly liquefying it to molten rock and destabilizing its core. The shockwave from the weapon damages the Stargazer, fatally wounding Captain Ruhalter (David Bryan Jackson) and advancing the young Jean-Luc Picard (Patrick Stewart) to acting captain. The Stargazer and several other Starfleet vessels successfully destroy most of the stellar debris emanating from the liquefied planet so as to prevent collisions with several inhabited planets nearby.

The game then moves to 2368 as Commander Benjamin Sisko (Avery Brooks), having recently been assigned command of the experimental USS Defiant, takes his ship to the Itari system to test it out. En route, he encounters a mysterious phenomenon which prevents warp, along with several Romulan Warbirds. They intend to apprehend a dangerous fugitive allegedly responsible for the deaths of many Romulans. Sisko confronts the Romulans over their illegal presence in Federation space and is taken prisoner. Captain Jean-Luc Picard, now in command of the Galaxy-class USS Enterprise (NCC-1701-D), is sent to the system to locate and recover the Defiant and her crew. After learning of the presence of warp inhibitors in the system, the Enterprise destroys them and Picard's team assaults a Romulan starbase in the area, saving the Defiant.

The game then advances to 2380, following the end of the Dominion War (see "What You Leave Behind"), the return of the USS Voyager from the Delta Quadrant (see "Endgame"), and the collapse of the Romulan Empire (see Star Trek: Nemesis). Captain Picard and the Sovereign-class USS Enterprise (NCC-1701-E), along with Admiral Janeway (Kate Mulgrew) aboard the USS Voyager, are engaged in discussions with T'Uerell, who is escorted by several powerful Borg vessels. She reveals that she has assumed the role of the Borg Queen, having reformed the Collective into a tool of total logic in pursuit of her goals to eliminate all that is illogical in the galaxy. When Starfleet refuse to surrender, T'Uerell has the Borg begin to assimilate civilians on nearby planets. However, Picard and Janeway are able to co-ordinate a mass evacuation of the system.
