Most of the live-action scenes including Dorn appear at the game's onset, before the game involves the player in the story. At the conclusion, I felt involved, but Dorn played only a minor part here. Though the live-action sequences are good, all the game voices are superb. John Hansen, who speaks for the player, does so superbly. When the player should feel nervous, Hansen has a detectable note a fear in his voice.
Every voice spoken outside the live-action scenes is a joy to hear.
Brief parts of the end-game, where John Hansen does not speak for the player, disappoint. Since Hansen's voice was a favorite aspect of the game, the absence is hard to ignore. Mission Critical features an amazing video engine, able to stream video and sound from a double speed CD ROM effortlessly, while retaining video quality. The game plays comfortably on a 486-33 with 4 megabytes of memory. Mission Critical is a big game with a small footprint.
