Alias Cheats

When you are in the changing room and Sydney grabs the keycard and the
doors look and vx gas is released. Just grab the guitar and run to do
the door and keep hitting it. It will eventually fall down.

When at the end and you have to turn on all the fire alarms, one of them is in Basement 2. Note: After you turn on all the alarms you must hurry to the ballroom and fight three men, then find Dixon and escape.

Complete the game once then on the New Game screen press L1 and R1.

Enter BIGDOGS as a cheat password.

If your health is low and Sydney is breathing like she is tired, get away from all targets and wait for awhile. Her health meter will go back up. Note: This may take awhile.
