A great variant of Cortex Plus Action Roleplaying. 8 Pages of rules, 4 pages of setting background, 16 pages dedicated to a rich character build system, and then a 40 page adventure.
About the only thing missing here are character advancement rules, but these are easy enough to extract from one of the other Cortex Plus action rulesets.
And at $5.00 you are not going to find a cheaper introduction to the Cortex Plus system, which is a lot of fun and makes for fast engaging games.
