Seriously, color me SOLD on this concept. Ken Levine of Irrational Games discussed implementing new "heavy hitters" in the upcoming BioShock Infinite as a way to break up the potential monotony found in the game. He is calling them "Motorized Patriots." And yes, one will be a mechanical George Washington.
Beating all of the Motorized Patriots—please tell me there is an Abe Lincoln and a Thomas Jefferson in there...or at least a John Hancock who wields a giant quill sword—will grant players access to a unique gun that cannot be found or purchased in any other way. Think of the ultimate weapons from a Final Fantasy game.
I've always been a bit excited for the new BioShock, but this idea has made me almost giddy.
