For only 4 dollars? Count me in!
So the Battle of Forli DLC is the first of missing sequence in your memory and it is sequence 12.Sequence 13 is called "The Bonfire of Vanities." Which is set to come out sometime in Febuary, for I think 5 dollars (It is also DLC). So the Battle of Forli takes place in Romagna "Forli". The Orsi Brothers attack Forli because they want something very important that you have but I won't say what so I won't spoil it. So you have to escort Catarina Sforza and Niccolo Machiavelli throughout the city while fighting guards to save Catarina's children. So when you reach her children she is misssing 2. A boy and a girl, the Orsi Brothers are using the 2 children for collateral for the important artifact they want and you have.
So then you have to go and save Caterina's children in a certain amount of time, and they are both in different locations. So you kill one of the brothers and you have to chase down the other brother. So you chase him down because he has the artifact. So when you assasinate him he stabs you in the stomach. You have the artifact in your hand and as you pass out you drop the artifact and a man in a black robe who has a missing finger picks it up and you black out. So you wake up and Caterina is right next to you happy that you woke up. Then Ezio remembers that a man in a black robe with a missing finger took the artifact. Then, she recommends to go to a church that is full with monks with robes. Then you save a monk who is being attacked by guards and he gives you information of the man who stole it. (You can also use DaVinci's flying machine whenever you want.)
Then that is when the memory "corrupts" again. Im guessing when the "Bonfire of Vanities" starts you have to hunt down the man who took the artifact from you. So over all I think that this DLC was well worth the 4 dollars. So go out and buy it, it was entertaining, fun, and only 4 dollars.
