The Hidden Blade Assassin's Creed in Depth

In Assassin's Creed: Brotherhood, we come across with many Leonardo's war machine. Here's some fact and fiction I dug up from the net.

Machine Gun

You know, this reminds me of Delta Force: Black Hawk Down, where you hop onto a Humvee and cut a path of carnage with the 50 caliber machine gun. In actually fact, Leonardo did invented the machine gun. However, it looks like this:

The multi-barrels feature gives the gun an edge to massacre people.

Bomber

From what I know, Leonardo invented the flying machine, but not a bomber. In my opinion, the in-game bomber design simply just can't work out. Not something very sophisticate, just use some common sense. How can you fire at people while both of your hands are grabbing the beam that controls the machine? Furthermore, you need to reload that sucker after every shot. And, how much ammo can you carry if you are clinging on something that relies on bonfire to boost? Plus, the ammo has to be special, it is no a projectile that simply just kill things, it is something that will create a burning spot upon contact, pretty much like a Renaissance napalm bomb, which I think it can't be created by the technology at that time. Lastly, this design is impractical if the designated area is soaked with water after a rain. So I think the bomber is fictional.

Naval Cannon

Hehe! This one looks like a mini-MRLS mounted on a boat. And yes, Leonardo did invented a naval cannon. Here's how it looks like:

Tank

Out of so many war machine, I think the tank is the most realistic. Ya, Leonardo did invented that, and the in-game design is the same as the original sketches.

And before I end this thread, there are several more Leonardo's machine that are omitted by Ubisoft.

Renaissance Robot

Cluster Bomb

Scythed Chariots

Barrage Cannon

Wall Defense

Helicopter

Giant crossbow

Improved Catapult

Improved Fortress

Dismountable Cannon

Siege Weapon

There are more inventions that I can't get a picture like the scuba diving gears and the revolving bridge. And before you guys ask, yes, Leonardo invented the parachute. Isn't he a genius?
