When worlds collide, they go BOOM! What do you get when you insert Assassin's Creed's Altair into Metal Gear Solid 4? Well you get this video clip, which shows the smoking assassin watching patiently while countless soldiers get slaughtered before leaping into action and finally revealing what he's been hiding beneath that robe...Solid Snake! Feel free to insert your own "Is that a Solid Snake under your robe?" jokes in the comments section, while Kotaku try to figure out where the hell this clips came from.
