Well, I've looked at logic.txt and hero.txt and armgen.lua..
But I don't see anything I can understand but logic.txt everything else is gibberish.. maybe if I understood what the prime/number labels were doing in the script I would get it.. but reading it..
I'm lost 
I think I get what this array does in logic.txt.. but I'm thinking if I change any numbers.. it won't make the creature automatic spawn increase.. with the difficulty settings..
