Through my battles with Osgood Slaughters disease (Its not really a disease, just extremely painful growing pain in which my knees locked up) and spraining my ankle, i have thought about making the crutch itsled into an airgun. Just seal the back paart of it, hook up a pumo of co2 tank to it, hook it up with a solinoid to a magazine of some sort, (never got that far) and poof, you have yourse;f a crutch gun.
I cant wait for my copy to come in.....stupid shipping. Although i played it at a friends house....and i needed to buy a new pair of pants after seeing it.
