Source Pack Beta is a slim blue covered work containing computer generated stats. The 45 Scorpion Men and 54 Broos are up from the slime and in from the dark, ready to make life in your campaign just a little uncertain. Greg Stafford included a page of background on each of the two main subjects, but other source material and the artwork total are nil. All these supplements have that fresh from the dot matrix printer (with fading ribbon) look. Ray could have at least given them colorful names or some other distinction. The chaotic features are particularly boring. Most are of the "6 point armor, leap 10 meters, bore reader at will" variety.
