Mockery Breed Murder Birds is one of this authors better works. It details effectively were-cassowaries. Though originally a creation of Pentex, these effectively were-birds are now warriors of Gaia. Although they might be hard to fit into a campaign, the mechanics of these murder birds are quite playable.
As a Pay What You want title the Tabletop Gaming Club recommends that everyone pick up a copy of this booklet for their Werewolf campaigns.
