This is a complete game system used for Zombie Apoc settings. Works very similar to any D20 type game system. The rules are easy if you have any experience in D&D. There is an addition to this as well called Against The dead Kicking and Screaming. I have only used the core rules and it works out nicely. I didn't notice any pages that are not complete. Is a good download.
