Hiding levels
By using Octavianus, on almost every level where you have to hide from Roman guards, one of them will have a "Gold fortune coin" on him. In each case, just remember that if you walk away a door that will make the game load for the next scene, all thing will be reset to what it was when you first arrived, except for the fortune coins. This is helpful if you are being chased and do not know where to go.

Also, if you happen to strike someone and a guard or a maid do hear it, take the uniform of the person you just hit and walk through the one that is coming. He will notice you and forget the sound that he heard.Then, get out of his sight and he will go back to whatever he was doing. You will then be able to hide the body and take all the time you want.

Alternate costumes
Finish every gladiator challenge completely to access a gorilla costume for Agrippa.

Keep on purchasing items from merchants to access various costumes and hair for Octavianus: Onion Head, Pansa Robe, Splitting Headache, and the Chameleon Suit.
