Part 1: In the lab.

You awaken sitting on a metal bench, camera in first person. The floor beneath you is white, nondescript tiles. You can only see for a couple of meters before a dense black fog obstructs your vision. Your controller is locked, forcing you to look straight ahead at the doctor in front of you. You struggle a little but will soon discover that you have a large metal contraption bolted to your skull and held in place by cables suspended from the ceiling, so the struggling is limited by this.

You have no HUD as you are not yet in a dropsuit.

(These environmental limitations allow a single tutorial to be created for all races. The model used for the doctor can change based on race selection.)

Doctor: "Don't try to move. You've just undergone a major surgery. Do you remember your name?"

The doctor taps out notes on his mad futuristic medical notebook as the PS3 keyboard pops up on screen for the character's name to be selected. Once this has been done, the doctor continues.

Doctor: "Good. Alright. I'm Doctor [racially variable last name]. It takes seventy-two hours, for all cognitive, memory and motor functions to be mapped and routed through the neuro-interface socket implanted in your head. Don't. Move."

The final line delivered tensely as you bring your hands into your field of view and to your head.

Doctor: "A temporary solution until the procedure is complete. Try and relax..."

You sit there for about ten seconds watching him go about his sciencey business until an alert buzzes out of the machinery overhead, then a hiss as the cables and hoses attached to your skull drop to the ground, having been released from the ceiling. You wobble for a minute, threatening to lose balance before looking back at the doctor.

Aiming controls are unlocked. You can now look around freely.

Doctor: "Alright, we're done in here. Do me a favour and watch me walk around the room."

The doctor paces back and forth and the player has to follow with their view. This could be used to automatically decide whether to invert these controls.

Doctor: "Everything seems normal."

A nurse enters and the doctor and nurse lift you down off the bench into a wheelchair, which the nurse pushes out of the room and down a hallway. Eventually the hallway ends and you are carted into a room, placed on a bed and left to fade to black.

An indeterminate amount of time later, you awaken and look at the bed side table. There's a grenade, pin intact.
You lift the grenade and beneath it is a handwritten note which you lift to read. It reads "KILL YOURSELF."

Aiming controls remain unlocked and you are free to look around the room but unable to move. Your little room has no windows, the door is as good as a wall and the wheelchair is gone. It's just you, a bed, a table and a note.

Oh, and the grenade. A prompt comes up onscreen. "Hold L2 to cook a grenade."

Whether you cook it or throw it, the grenade exploding in your room kills you.
