Prerelease:Star Trek: 25th Anniversary (NES)
This page details prerelease information and/or media for Star Trek: 25th Anniversary (NES).
Split these two pictures to talk about the differences properly.
Everybody's favorite honorable space barbarians, who neither appear nor get mentioned in the final game. It seems the developers originally wanted Klingons to be the main antagonists before deciding to use Romulans instead.
The final game does contain one Klingon-related leftover, as the HUD shows a Klingon battlecruiser when fighting the Romulan Bird of Prey. (This also inadvertently doubles as a callback, as Romulans did pilot Klingon ships in the episode The Enterprise Incident.)
The image on the right shows four crewmen on the Transporter platform, whereas the final game's away teams are no larger than 3.
