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: 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: 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.
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.
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.
