Fixes:
1. Grenade bug.
All NPC had 100 in strength so I changed it to the same value as their dexterity.
(It varies between 48 and 93) 

2. Breath bug.
It costs 250 Breath Points to fire a single shot and 500 to fire a burst and that
causes the mercs to get winded after a shorter firefight. A reduction of the
values to 100 and 250 solved that issue.

Installation:
Just copy the files to Hired Guns\basis\scripts\logic and run the game. The
changes will be active imeditially but I recommend to start a new game.
