Moulder Pitfighters is a map where you create beasts by mutating them, currently there is only 5 base "animals" humans, orcs, skaven, ogres and rat ogres. The background is from Warhammer Fantasy, you fight in the city of Hell Pit.'
The first thing you need to do is to buy a labaratory(there is one for each, and its impossible to have more than one). This enables you to flee into your lab, make the lesser animals(humans, orcs and skaven). Also this gives you food which you need to recruit animals.
To mutate an animal you need to buy it in the market(go right when you enter Hell Pit) there you can buy all the animals and all the mutations. Mutations go into inventory so an animal can have a max of 6 mutations. This includes your Master Moulder hero.
There is 4 different fighting pits, they vary in what level the beasts are there.
There is also an Ally/Unally system so you can attack you fellow players(when unallying they automaticly unallies you to).
To win you must defeat Morkskittar, an master moulder which have mutated himself beyond recognition. You must also stop the other players from doing this at all costs...
