Glitch: Falling sky On any level where you are outside, take out a projectile weapon such as pistol, shotgun, machine gun, etc. Look straight up into the sky until you cannot look up any higher. Fire a few shots straight up into the sky. If you keep looking up, you will see marble size pieces of the sky fall down onto you.
Hint: Annoyed people In every level are small items that you can pick up. Find such an item and look for a friendly person (green target cursor). Throw and hit the person with the item to get random reactions. Do not try this on an enemy unless you want to get shot.
Hint: Extra items When you are low on items, go up behind a security guard and make sure there are no robots, other guards, or cameras around. Hit him with the crowbar. He should die instantly and have bullets, knockout ammo, explosives, and a few other items that are very useful. Information in this section was contributed by CedeRi. Hint: Control credits: Press Up to roll the credits faster or press Down to slow the credits
Glitch: Ghost toilet If you get to the mole people tunnels, at one of the ends is a women's bathroom that has its door leaning next to the door. When you walk in, you should see two mirrors to your right. Walk to face them, then put away any weapons you may have out for visibility. On the left hand mirror, look at an angle to the right slightly. There will be a black toilet in the reflection, but there in the game
Hint: Money $$$ Money When you are at the Lucky Money in Hong Kong, get Inside the club and go where the door girl is located. Kill her, then right click on her to get some credits.
Cheat mode Enter the Goals/Notes/Images screen. Press L2, R2, L1, R1, Start(3) to display another tab on this screen with the following options: God Full Health Full Energy Full Ammo Full Mods All Skills Full Credits Tantalus Some options may need to be re-enabled after entering a new area. The Tantalus option allows you to destroy a highlighted object during game play. Note: This has no effect on indestructible objects.
Hint: Killing robots You can kill robots with just about any weapon, but it will take awhile when using a shotgun. With a normal unmodified clip, it will take over ten clips, and you will need God mode.
Glitch: Retain inventory After becoming detained, press Square when the "Area Unknown, Time Unknown" text appears to drop all of your items. Wait a few seconds, then collect them again. If timed correctly, you can keep all your items.
Hint: Slow reaction time Standard (non-Boss) enemies you encounter have a slow reaction time when spotting you. The farther away you are from the enemy, the longer it will take for him to spot you. All enemies except for Bosses will say something such as "What was that noise?" or "Who's there?". If this happens, it does not mean that they know you are there -- they only think that you are there. If you hear en enemy say something similar to that, look for cover, because they will investigate. This trick will not help you if you are out in the open.
