Assassin's Creed: Brotherhood/Controls

Puppeteering concept
When in the Animus, you control your avatar through the system's hardware. Different controls correspond to parts of your avatar's body (and Desmond's in real life), for the purpose of making control more intuitive.

You are naturally in low profile, where most actions don't alert guards and you won't draw undue attention. When in high profile (accessed with psx: R2/), you can perform more athletic and aggressive actions, although it is also easier to alert the guards.

General
These actions are used throughout the game, without regard to what profile you are in. The direction pad can be set to include any shortcuts you want by selecting the weapon or equipment item from the selector wheel and pressing the direction pad where you want to set it.

Multiplayer
In ../Multiplayer/, the controls are pared down to a simpler scheme and some buttons have different actions.
