Assassin's Creed: Revelations

• The map opens up a lot earlier than previous games. You can free all Assassin Dens right after the respective tutorial. Freeing up all Assassin Dens and assigning Master Assassins to them unlocks Master Armor, Sword and Dagger, all best-in-slot for the entire game.

• You can refill bombs at any Bomb Station, assuming you have the materials. But you can't change the type of bombs you carry unless you go to specific locations.

• Unlike Brotherhood, buying buildings raises your Notoriety. Easiest way to reduce notoriety is bribing a herald and running far enough for him to respawn.

• Books and Landmarks are a massive money sink and provide no bonuses outside of completionist tendencies.

• If you are going for all achievements, get the tax collector before fully freeing or upgrading Constantinople as they become incredibly rare once the city is safe.

• You cannot bomb all the wells open - the counter includes several that were removed from the game.

• The Tower Defence game is optional aside from the tutorial. If you're careful about dropping your Notoriety it won't come up, and if you've got a max rank recruit running a district then that area is safe permanently. You can get the Iron Curtain achievement by replaying the defense game tutorial from Sequence 2, and ignoring the cannon tooltips - they'll go away on their own. The achievement can be completed by making all districts secure.

• The Mediterranean Defense mini-game is optional outside of the tutorial and provides no bonuses to the main gameplay outside of Assassin recruit XP, money and bomb ingredients and can be safely ignored after leveling your Assassins.

• The Templar control % increases by a random amount each time the player gets their bank payout. Similarly the Assassin control % deceases by a random amount when the city is controlled by Assassins.

• Some equipment and books are sold in stores in the second city of the game.

• The DLC is a set of first person puzzle levels, giving some backstory to Subject 16. It can be accessed from the Animus Island and gives no advantages in the main game.
