Warning for Desura users: you need to manually make a backup of patch.dat and patch.fat file in your Data_Win32 folder inside Far Cry 2 directory just to be safe. Mini-mod aiming to decrease costs for weapons and upgrades, increase damage, reduce recoil and reduce weapon degradation, while not taking away the immersion and realism already present in Far Cry 2.
Further examples of the effectiveness of the new upgrades. The weapons now jam less frequently (when upgraded), are far more accurate (while not deadly accurate), the recoil is reduced (you still need to control the weapon as it moves when firing) and more damage is dealt (though not too much - enemies will still survive from one shots to the chest, but nowhere near as frequently!)
