Worth every penny.
One of the things I like most the SCI-FI part of the game. The ending. One of the best I've played.
This DLC worth every penny due to the story (sci fiction style), the length (more than 3 hours) and the addition to the Assassin Creed world (Da Vinci real painting set in a very intriguing story).
There are other DLC to Assassin Creed II that I haven't downloaded yet. However, by completing this, I feel courious in playing them.
I do recommend to download and play this DLC.
There is not much to tell for a DLC for a long review...........................................................................................................................................................
Thanks for reading.
