Simply check which Wasteland Bestiary mods you have and download the proper patch.
If you're looking for something bigger and more complex, use the full version of Mutant Menagerie - Life Finds A Way (SCORGE patch is here)
If you face with SCOURGE first time.
What does SCOURGE do? It addresses the bullet-sponge issue by allowing you to adjust HP, DR, EN, and SPEED, SCALE and etc, for each race.
If you prefer not to make tweaks, the default values in SCOURGE work well too.
I recommend using a damage-normalized mod like "TRUE DAMAGE" for an enhanced experience.
If you use true damage and munitions or vanilla only ammo - use my rebalance patch.
And here you can find more SCOURGE patches.
