About Mission Critical
Mission Critical is an adventure about the sole surviving crewman aboard a crippled vessel, where a ruptured hull is leaking air and the weapons systems are down. Your mission might have ended fifteen years of interstellar war, but first you must stay alive.
From ship to planet
The story takes you from the bridge of the battlecruiser USS Lexington to the surface of Persephone, a stark planet of endless rock spires beneath crackling electrical storms. You salvage the damaged starship, survive a battle in deep space and explore a vast alien installation. There, you open a crystalline portal to another time and face a choice that will decide the fate of mankind.
Exploration and combat
You explore a nine-level, twenty-second-century battlecruiser and an alien world in smooth-scrolling 3D, with character interaction and space combat. You also align a wormhole across four dimensions.
Presentation
Full-motion video is integrated into a 3D-animated world, with layered sound effects and a musical score.
