Sounds like a pretty cool story :D
Just out of interest do you playtest these first or have you done this long enough that you know what's going to work? I've been somewhat thinking of doing a similar thing (though in planning it is somewhat CoD specific) however I feel a need to playtest them first as the shorts that I wrote are the first time I've actually done something generic, I usually have people send me their characters and then make a story around them.
