While tranporting an extremely dangerous form of life, the aircraft carrier "Heimdall" is attacked by terrorists. The ship transmits a "Mayday" message and then falls silent. Your job is to board the ship and determine what has happened to the ship, crew, and the mysterious life form. The members of the species called Homo Sapiens had long considered themselves to be the most important life form inhabiting the planet Earth. They chose to ignore the fact that their extinction would have little, if any, effect on the majority of the Earth's living creatures. The overwhelming majority of the ecosystem was comprised of plants, bacteria and viruses; species that would no more be endangered by Man's extinction than they were by the passing of the dinosaurs. Man, the "arrogant ape" truly existed at the mercy of these architects of our world. During the turbulent period of the early 21st century, the men of Earth were embroiled in military action over worldwide environmental issues. As terrorism and unrest grew, various alliances had been formed by the groups in conflict. Military action flared, and Man again resumed his destructive path. In the middle of this conflict an ancient, and extremely dangerous, form of life has been discovered on a remote Pacific island that is being used as a military facility. In order to study this unique phenomena under secure circumstances, the decision is made to transport them to an appropriate laboratory under the protection of the military, using the ultra-modern nuclear aircraft carrier 'Heimdall'. During the voyage the Heimdall is the target of a terrorist attack. The ship transmits a 'Mayday' message and then falls silent. Your job as a member of a hand-picked squad is to board the Heimdall and determine what has happened to the ship, crew, and the mysterious life form. Carrier is a full 3D adventure that will immerse the player in the mystery and excitement of a voyage to Hell. Multiple levels will challenge you as you seek to unlock the mystery of the giant aircraft carrier and its cargo. Taking advantage of the exciting capabilities of the Dreamcast system, Carrier will set new standards in the action/adventure category.
