Once there, he finds Dr. Tolian Soran, a scientist and madman hell bent on returning to the Nexus, a paradise dimension. Soran escapes and the "Enterprise" goes on various missions to try to find him. To return to the Nexus, Soran intends on destroying stars in order to cause the Nexus (due to loss of the stars' gravity) to pass near Veridian III. The player needs to guess which planets Soran intends to destroy in order to pursue him. Apart from being based on the film, the game is also a semi-sequel to "", since the aliens from that game, the Chodak, make an appearance. The overall science fiction universe of these titles, is based on , a television show that aired between 1987 and 1994, itself developed from the earlier "Star Trek" show of the late 1960s. The game combines many computer game genres, and follows the main non-linear philosophy of alternate paths to complete the game, followed in other Star Trek games. The major portion of the game occurs in Stellar Cartography (also appearing in the film, although only for some minutes) where the player plans their next moves, the main opponents being time and Soran. This part of the game includes the strategic part where the player has to calculate and guess where Soran could be, in order to travel there and stop him before he destroys the system. When a crew member beams to a planet or space station, the game switches to first-person action/adventure. The main objective of every away mission is finding and fighting with Soran, who beams away seconds before being killed by the player. The mission is then successful; however, not all away missions need to be successful to win the game. Enemy ships are encountered while in space. The game then switches to pure tactical/simulator where the player controls the "Enterprise" against the enemy ship(s). The fighting system is simplified over the extremely difficult tactical part of "A Final Unity". Producer Simon Finch explained the game's storytelling philosophy: "We were trying to put the player into the situation that the characters were in the movie "Generations", but we wanted to let them do what they wanted to do, and have the situations deviate fairly far from the film." Concerning the gameplay style, he commented, "We definitely wanted to teach players that violence isn't always the right solution, but we never wanted to water down gameplay by taking that option away from them." "Star Trek Generations" received mediocre reviews.
