What you get: A 26-page book on Assassins and subclasses for OSRIC and compatible games. The sub classes are interesting enough to keep my attention (I liked the Ninja and the Bounty Hunter).
What struck me as odd though was how it was written. I am not 100% sure English was the first language of the author. There were some very awkward word choices and sentences through out. It also uses a 3rd party skill system that I didn't have. With the OGL the best to do would be include it.
The layout is clean but uninspired (a single column of text) and there is no art at all.
The concept is good, the execution of it though is poor.
