For those of you who have been unfortunate and not been able to play the original Wasteland, I wanted to write up a breakdown of how it's health system worked. Many of you may have seen people speaking of unconscious or critical condition in the threads talking about character's HP. You may have also seen abbreviations such as UNC, CRT, or MRT. Well here is Wasteland's system explained in detail. This breakdown demonstrates the mechanics of the health system. The actual numbers and ranges may be off but this should still give you a good idea of how HP was handled in Wasteland.
Wasteland had a health system which did not include healing items of any sort. There was a first aid skill and doctor skill. That was it. It featured a system with different condition levels which I have never seen before or since and I find to have been extremely innovative. We will use a character with a MAXCON or max hp of 30 as an example. Here is the health ranges broken down:
30 - 1 = Normal status
0 - -9 = Unconscious (UNC)
-10 - -19 = Serious (SER)
-20 - -29 = Critical (CRT)
-30 - -39 = Mortal (MRT)
-40 - -49 = Comatose (COM)
-50 or less = Deceased (DEC)
As you can see, the system let you go far into negative health before a character would be permanently dead. Outside of combat, health from -9 (UNC) or higher would heal simply by passing time. However anything -10 (SER) or worse would slowly get worse by passing time. You would use first aid and doctor skills to stabilize these characters to an UNC state. You could also pay an NPC doctor to heal and stabilize wounded party members. It would take a significant amount of in game time for a character to go from serious condition to dead.
In combat, I don't think health regenerated with the exception of unconscious characters. Anything worse would slowly get worse same as outside of combat unless treated by a medical skill. Characters below 0 health would be unusable and would have their turn skipped until their hp reached 1.
I hope this guide helps anyone not familiar with the Wasteland system to understand how health was handled originally.
