Weapon upgrade – Zombie Objective Review

I have played all three Enemy strike games they are magnificent and the Enemy's for all three versions are imaginative. But in the Zombie version I propose not just gun's & knifes but maybe a Bow & Arrow type weapon like a cross bow and a bow that the player can upgrade from say starting out with a wood bow to a stainless steel bow & upgrade the Arrows.
