Areas that could be explored included main engineering, bridge, mess hall, sickbay, astrometrics, and the cargo bay. It allowed players to explore various decks of the starship, in great detail – accurately portraying areas of the ship seen on the televised series, but also expanding on the Elite Force universe as well. The second feature was a 'Virtual Voyager' sub-game, accessed separately from the main game, but taking place shortly before the game's final level. The first was a voice pack that added Jeri Ryan to the main game as Seven of Nine - the original featured a replacement voice artist, Joan Buddenhagen. The pack added three main features to the game. It was created by Raven Software and published by Activision in May 2001. The Star Trek: Voyager - Elite Force expansion pack is an add-on to the earlier of the two Elite Force games, Star Trek: Voyager - Elite Force.
