Mission Critical description

Mission Critical: The Ultimate Game of Survival

In Mission Critical, your survival hangs by a thread aboard the crippled battlecruiser USS Lexington. With the hull ruptured, air escaping into the void, and weapons systems completely offline, you are the last surviving crew member. Your mission was to end a fifteen-year interstellar war, but you are now faced with a dire choice: stay alive at all costs.

This gripping adventure immerses you in a perilous journey from the bridge to the stark and deadly planet Persephone. Traverse an alien landscape filled with jagged rock spires and electrical storms, where you will uncover a crystalline portal to another time. As you navigate the challenges ahead, you must confront the profound question: What does it mean to be human?

Experience nonstop action as you salvage the starship and engage in intense battles in deep space. With seamless exploration of a vast alien installation, align a wormhole across four dimensions, and decide the future of humanity. Engulf yourself in a dazzling virtual world filled with full-motion video, immersive sound effects, and a captivating musical score that brings this gripping odyssey to life.
