/* Time based Damage works as follows: 
	1) There are several types of timebased damage:

		#define DMG_PARALYZE		(1 << 14)	// slows affected creature down
		#define DMG_NERVEGAS		(1 << 15)	// nerve toxins, very bad
		#define DMG_POISON			(1 << 16)	// blood poisioning
		#define DMG_RADIATION		(1 << 17)	// radiation exposure
		#define DMG_DROWNRECOVER	(1 << 18)	// drown recovery
		#define DMG_ACID			(1 << 19)	// toxic chemicals or acid burns
		#define DMG_SLOWBURN		(1 << 20)	// in an oven
		#define DMG_SLOWFREEZE		(1 << 21)	// in a subzero freezer

	2) A new hit inflicting tbd restarts the tbd counter - each monster has an 8bit counter,
		per damage type. The counter is decremented every second, so the maximum time 
		an effect will last is 255/60 = 4.25 minutes.  Of course, staying within the radius
		of a damaging effect like fire, nervegas, radiation will continually reset the counter to max.

	3) Every second that a tbd counter is running, the player takes damage.  The damage
		is determined by the type of tdb.  
			Paralyze		- 1/2 movement rate, 30 second duration.
			Nervegas		- 5 points per second, 16 second duration = 80 points max dose.
			Poison			- 2 points per second, 25 second duration = 50 points max dose.
			Radiation		- 1 point per second, 50 second duration = 50 points max dose.
			Drown			- 5 points per second, 2 second duration.
			Acid/Chemical	- 5 points per second, 10 second duration = 50 points max.
			Burn			- 10 points per second, 2 second duration.
			Freeze			- 3 points per second, 10 second duration = 30 points max.

	4) Certain actions or countermeasures counteract the damaging effects of tbds:

		Armor/Heater/Cooler - Chemical(acid),burn, freeze all do damage to armor power, then to body
							- recharged by suit recharger
		Air In Lungs		- drowning damage is done to air in lungs first, then to body
							- recharged by poking head out of water
							- 10 seconds if swiming fast
		Air In SCUBA		- drowning damage is done to air in tanks first, then to body
							- 2 minutes in tanks. Need new tank once empty.
		Radiation Syringe	- Each syringe full provides protection vs one radiation dosage
		Antitoxin Syringe	- Each syringe full provides protection vs one poisoning (nervegas or poison).
		Health kit			- Immediate stop to acid/chemical, fire or freeze damage.
		Radiation Shower	- Immediate stop to radiation damage, acid/chemical or fire damage.

/*
THE POWER SUIT

The Suit provides 3 main functions: Protection, Notification and Augmentation. 
Some functions are automatic, some require power. 
The player gets the suit shortly after getting off the train in C1A0 and it stays
with him for the entire game.

Protection

	Heat/Cold
		When the player enters a hot/cold area, the heating/cooling indicator on the suit 
		will come on and the battery will drain while the player stays in the area. 
		After the battery is dead, the player starts to take damage. 
		This feature is built into the suit and is automatically engaged.
	Radiation Syringe
		This will cause the player to be immune from the effects of radiation for N seconds. Single use item.
	Anti-Toxin Syringe
		This will cure the player from being poisoned. Single use item.
	Health
		Small (1st aid kits, food, etc.)
		Large (boxes on walls)
	Armor
		The armor works using energy to create a protective field that deflects a
		percentage of damage projectile and explosive attacks. After the armor has been deployed,
		it will attempt to recharge itself to full capacity with the energy reserves from the battery.
		It takes the armor N seconds to fully charge. 

Notification (via the HUD)

x	Health
x	Ammo  
x	Automatic Health Care
		Notifies the player when automatic healing has been engaged. 
x	Geiger counter
		Classic Geiger counter sound and status bar at top of HUD 
		alerts player to dangerous levels of radiation. This is not visible when radiation levels are normal.
x	Poison
	Armor
		Displays the current level of armor. 

Augmentation 

	Reanimation (w/adrenaline)
		Causes the player to come back to life after he has been dead for 3 seconds. 
		Will not work if player was gibbed. Single use.
	Long Jump
		Used by hitting the ??? key(s). Caused the player to further than normal.
	SCUBA	
		Used automatically after picked up and after player enters the water. 
		Works for N seconds. Single use.	
	
Things powered by the battery

	Armor		
		Uses N watts for every M units of damage.
	Heat/Cool	
		Uses N watts for every second in hot/cold area.
	Long Jump	
		Uses N watts for every jump.
	Alien Cloak	
		Uses N watts for each use. Each use lasts M seconds.
	Alien Shield	
		Augments armor. Reduces Armor drain by one half
