Aliens is all about creating new “race as class” Alien types tailored for your campaign (or completely made at random.) The first chunk of the supplement is an easy step-by-step guide to cherry pick or randomly roll up features and characteristics of the new alien race. When it’s all wrapped up, you tally up XP value based on the results. This is what it takes to reach level 2 for the character, and each level after doubles that value. Easy peasy.
But he doesn’t stop there — He then presents 5 sample alien classes, each one with a full page write up and full colored artwork by the incredibly awesome Khairul Hisham.
Pros: A really fun, random, old-school style method of generating new and unique alien races to populate your game. Once again, good layout and the artwork rocks.
Quibbles: The overwhelming sense of guilt I have for only paying a buck for this.
