In this mod the ammo quantity and the capacity of medkits and armors are decreased by about a half. The damage of some weapons is also decreased by 10-20%. In addition, when the game starts your health level is only 25, that makes a sense for numerous medkits at the beginning of the game. Monsters are untouched except the final boss — Cyberdemon — its strength is doubled.
Surely it depends on the way you are playing, but according to my own experience, the original Doom 3 is overstocked with ammunition. The need to search and grab all the secret storages and to save your ammunition down to the pistol bullets is the main point of this mod.

This mod is balanced for the Veteran difficulty, although it can be used with any difficulty level. I suppose that playing this mod on the Nightmare will be very difficult.
