Assassin's Creed: Bloodlines/Upgrades

The upgrades are a handy thing in this game, as they are pretty useful and easy to get. From the Memory Select screen, choose "Upgrades" and you'll be brought to a new menu. You can also watch the total sum of Bronze, Silver and Gold Templar Coins that you've collected. Each upgrade costs a certain amount of points. You get these points from collecting the aforementioned Templar Coins. Here's a list of the upgrades that are available:

Note that after upgrading necessary skills you'll need to hit the "Confirm" option in order to store the changes you have made, and then exit to the Memory Select screen.
