Shoot yourself with the gun

From Create Your Own Story

You see a burst of white light

And then...darkness

You open your eyes, and fined yourself trapped in a large metal cocoon, with only your face free.

You shake until you break free, and fall out.

Around you are countless others, tapped in similar metal cocoons, but they simply stair blindly forward.

Multiple computer screens lie in front of you, mostly showing static

You then understand...

All of these people are trapped in a fantasy world, and have no free will, simply doing the will of the machine.

You run up to the computer, and see an off switch

You turn off the machine

Turn the machine off

Walk away from the machine
