The intro movie will show the events leading to the current situation. Basically, a deadly meteor was approaching Earth on a collision curse and the impact of the Meteor would destroy all life on Earth. Therefore, project Eden was initiated with the goal of preserving humanity. Brave volunteers where put into cryogenic chambers and buried deep in the ground to hopefully be awaken and emerge later, once the coast is clear and rebuild humanity.
You will see your character put into Cryogenic sleep and sealed in a chamber. Then the meteor hits earth, destroying its atmosphere.
An emergency override awakens you many years later as the computer detects a threat. Follow the instructions of the female computer voice. She will have you run several diagnostics, including a vertical calibration which involves simply looking up or down (move mouse on PC)
After you are done with the diagnostics, look around the room. You will see several other chambers, but the volunteers there were not as lucky as you, as the system failed to awaken them and they now lay dead in their chambers.
Listen to the playback of the president speaking.
Approach the center console and activate it. It will run additional diagnostics.
Go to the door and open it. You will be blinded by the bright daylight at first. As you step out, you will see the whole area is in ruins.
Go left, and take another left, suddenly you will be ambushed by some enemy. Luckily, a friend will be there to help you. He will shoot the bandis, and then drive towards you in his buggy. Get into the passenger seat of the buggy and he will drive you to his HQ in Hagar Territory. He will introduce himself as Dan Hagar. Once you reach his base, exit the buggy, follow Dan, then talk to him. He will give you your first mission, Quell the Bandit Threat
