You are a rat, you are living in the ratscastle, that was left behind from the Builders you never know if they will come back, but at the moment there is peace in the ratscastle. The packs in war a long time are know living in trace, so it is time to explore other parts of the ratscastle where no pack lives, no one knows what there is, maybe the reason why the builders left, or only more danger...
Be a rat, a really rat with claws and a tail, eat what other would throw away and craw on all fours through your short and dirty life.
Rats! is an originally German RPG that I am translating into English the rules are quite simple so that we can start playing fast.
