Enter Triangle, Square, square, Right, Down, Left, R2, X, X.

The ending where 47 dies at the end of the game (on Requiem) is not the game's real ending. What you need to do to achieve the real ending is to move the left joystick (it may be mouse or keypad on PC) back and forth (during the credits) until a surprise occurs.

Note that you will need to quickly eliminate all the witnesses in the level. All the guards in the main chapel carry weapons so you should take them out first. Good luck!

On the final level Requiem -- where you have to wake up and kill all witnesses in the church -- there is a major glitch. As soon as you wake up, exit the church and head south. There will be two stone mausoleums (or sheds). Enter the one that is furthest away from you.

When the doors are closed, the guards cannot open them, and they will all come running down. You can keep opening and closing the doors as you please without worrying about all the guards rushing in to kill you.

It is possible to get enough money to purchase all upgrades but don't buy everything. Some upgrades are replaced by better upgrades, so you should only buy the ones that you are going to use. For example, there might be three levels of silencers but you may not want to waste money on the first and second upgrades, because you can only use the most powerful silencer.

Once you've a few more dollars and decided to upgrade your Silver Ballers for more killing power, try using long slides, magnum ammo, full auto, and take two Silver Ballers. Enjoy mayhem.
