This is why tables are very efficient. as you can just make up a key and a value. For example:

local zombies = {--Continue this array
[1] = "ArmyZombies"
}

Zombies [zombies[ChooseRandomZombie]]:Clone().Parent = worldspace.AliveZombies

This way you only need to have a table and let the ChooseRandomZombie index the table. So no need for a bunch of if statements. It'll directly access the array making so you can have the long list of zombie types and then the value indexes it. I'd explain more if needed because I typed this out on mobile.
