In Assassin's Creed: Brotherhood, several cheats can be activated after achieving 100% synchronization for all of the memories in any given sequence. They can only be used while replaying a memory and will disable progress from being recorded.
|Cheat Name||How To Unlock||Cheat Effect|
|Ride The Unicorn||Complete Sequence 1.||All horses are turned into unicorns and lightning effect is put on all weapons.|
|Buns of Steel||Complete Sequence 2.||Makes Ezio Auditore immune to damage.|
|Killing Spree||Complete Sequence 3.||During fights, Ezio can execute enemies instantly.|
|Sisterhood||Complete Sequence 4.||Makes all Assassins Guild Recruits female.|
|Ultimate Guild||Complete Sequence 5.||Raises all Assassin Recruits to the rank of Assassin.|
|Calling All Assassins||Complete Sequence 6.||No cooldown timer when calling Assassin Recruits.|
- It is possible to ride a unicorn outside of a replay, even if the cheat is not available or active. This can be done by riding a unicorn with the cheat active, then returning to the current memory and calling for a horse. By default, this summons the last mount ridden.
- A rare bug can occur when activating either "Sisterhood" or "Ultimate Guild", in that one or both of the cheats will be permanently activated outside of a memory replay. If this occurs with the latter cheat before at least 5 Assassin recruits obtain rank 10, it makes it impossible to acquire the "Raise 5 Assassins Recruits to Assassino Rank" guild challenge without some of them needing to be killed, as the Assassins created by the glitch would not be registered by the guild challenge.
- When "Ride the Unicorn" is activated, some weapons may not always glow.
