Mission Critical is an adventure game released in 1995 by Legend Entertainment. Though its main advertising point was the presence of Star Trek: The Next Generation actor Michael Dorn, he played a very small role in the game. The game also featured a leading role by American actress Patricia Charbonneau, best known for her role in the film Desert Hearts.
In Mission Critical, you play the sole survivor of the USS Lexington and USS Jericho, a pair of starships sent by the Alliance of Free States on a secret mission to a world far from Earth. You are the only person capable of completing the mission, and saving not only the Alliance, but thousands of star systems from total destruction.
Graphics and sound
The bulk of the game consists of 3D renderings (the entirety of the spaceship, and several other locations), presented in static screens with transitional animations between most areas. Cutscenes are in full screen video with live actors. A few locations were evidently too complex for the 3D renderers of the period, however, and in these cases the designers used a mixture of computer generated images and highly detailed, hand-painted backdrops, with some 2D animation effects to compensate for the lack of transition movies in these parts, though the painted backdrops are of a sufficient quality not to break the sense of immersion in the game.
The game utilises stereo sampled voice and sound effects, music being provided (like many games of the era) via MIDI, although the FMV cutscenes had the music incorporated in the sampled soundtrack. The voice, sound effects and music are of a uniformly good quality.
Technology
Like most DOS games, Mission Critical, though advanced for its time, is somewhat difficult to run on modern computers - it requires a soundcard compatible with those of the era, offers no windows executable, weighs in on three CDs and the strategy minigame runs much too fast on modern processors. There is a way to fix most of these problems, however, all three CDs can be copied and run from a single DVD with no additional modifications as long as the directory structure is preserved, many modern soundcards offer hardware support of "legacy" devices (though certain motherboards can stop this feature from working properly), and certain programs are available to artificially slow down modern CPUs to run the game at an appropriate speed. The game can also be run easily in emulators such as DosBox.
Send your zip code for ship cost - should be between $4.99 and $6.99 if you are in the continental US (listed August 2013).
