Remember that Prince of Persia game that eventually became the original Assassin's Creed? You may not have heard about it (unless you saw the gallery we posted earlier today of some just-released concept art for it).
Either way, you should get a kick out of this video—it shows some early footage of what the game may have looked like, had it not been made its own series. It definitely still looks like Assassin's Creed, especially in the details, but there's some Prince of Persia stuff going on as well.
The idea of a second assassin rolling out of the crowd to aid in your getaway is pretty sick as well. Check out the footage (skip to about 1:30 in the video) and tell us what you think in the comments or on Twitter.
