Solid Snake VS Arkham Asylum

Solid Snake is far and away the single most effective soldier on the planet. When he is tasked with eliminating a threat on one of the most secure facilities on Earth. Which also happens to house some of the most insane criminals on the the planet, Arkham Asylum. He has 72 hours to neutralize a terrorist plot that is somehow tied into Arkham. Infiltration, stealth, leave no trace, standard black ops mission. Any evidence of his or the military's involvement in penetrating Gotham's home for the criminally insane will be denied. Snake is on his own, against the most lethal and psychotic villains to ever walk the streets.

(I have lots of ideas, will be popping in with updates periodically, fairly good direction of where the story is headed, totally open to comments or ideas. Being a Solid Snake story, there has to be a cyborg ninja, torture, and a Metal Gear naturally. Feel free to suggest any villains from Arkham that Snake or his buddies should go up against, or any feedback, or to say hi.)
