I think this script could work well as a comic, it introduces the main characer and what kind of life he had before the world went to hell. There is some foreshadowing there, which is nice.
I do find the transition from the normal world to the robot apocalypse world too hasty. I know he ended up in coma thanks to his drink, but I'd like to see more form his life before the apocalypse. Besides robots walking around, what did excatly change about his life? Did he have a family?
Also, I think the ammount of "OH SH*T" is too much, nobody reacts like that. Since this is a comic, all you need is a drawing of the ruined world and a drawing of his expression reacting to that.
