ZLO - Zombie Loot Overhaul  

This mod edits not only the drop rates of the loot bags, but also the tier. The 3 tiers are the yellow, blue, and orange bags, with orange being the best loot. (Regular, Strong, Boss is what they're referred to in the game files). Adding specific items into the respective loot pools is also in consideration (i.e. gyrocopter parts being in the Boss loot bag pool).
