Thief - The Dark Project Thief 1 Ultimate Difficulty Mod v.1.0

Description
The goal of this mod is to radically raise the difficulty level.
* A lone guard who is alerted and makes a confirmed sighting of Garret or a body, searches for him, and gives up, will run to alert others instead of returning to his regular patrol. After that however, he will resume his patrol.
* The AI vision cones have been completely redesigned to given them better distance vision, a more accurate loss of acuity over distance, and to eliminate Garrets ability to use leaning tricks to blackjack guards while alerted.
* I have heavily modified the dynamics of noise creation as a result of Garrets footsteps. Running on wood and cobblestone now has the potential to alert guards within a few meters. This means you will have to *walk* up behind them for a successful blackjack. Also, creeping on marble, metal, or gravel is actually *quieter* and no longer alerts guards thus eliminating the need to tap the forward key and creep-crouch.
* Garret is now more visible to AIs as the visgem will indicate. To offset this new disadvantage, I have increased the bonus Garret receives for crouching and sticking close to walls.
* Bodies are now MUCH harder to hide. Forget about tossing your victim in a shadowy spot on a well patrolled hall. Only two things may effectively hide a body now: a physical barrier, or an area of nearly absolute darkness.
* The AI have been made faster, especially zombies (who are now a real threat to an experienced player!)
* Residual alertness on guards who have been raised to level 3 now increases their perceptiveness by a considerable margin.
* Yelling made by guards during combat or searching travels further and is heard more easily by other guards.
* Blackjacking someone makes a minor sound disturbance.
* A collapsing body makes a minor sound disturbance. (both of these are not loud enough to alert anyone but simply attract their attention if already alerted or perhaps illicit a "Who's their?"..."Musta been rats" response )

Usage instructions:
This project requires HD Texture Mod to be installed first
To play with the custom gamesys, your simplest option is to backup your old dark.gam and replace it with the new one. Load up Thief and be prepared to find a whole new challenge awaiting you in the missions you have grown to love. Any fan mission that doesn't use its own custom gamesys will experience the changes as well.
To restore your original Thief version, simply copy the DARK.GAM file you backed up back into the Thief directory.
