I will quickly support what the above reviewer has said, with an update and short additional comments.
Firstly, I've come to love every piece of work UKG Publishing puts out. If you're a fan of zombies, their Year of the Zombie series is by far the best supplemental material I've found for the kind of games I like to run and play.
These issues, and all the future ones as well (which ARE available now), do three things incredibly well:
1) They always start off with a short narrative describing ongoing characters and a setting. It really gets you in the mood to play.
2) The environments, new classes, weapons and equipment, is all very appropriate and well-designed for adding to a zombie campaign.
3) There's always a nice map or two, plus a few great NPCs or baddies, for you to use.
Long story short, there's some great fluff here, but the most important part is that these ALWAYS have some REAL, USABLE materials for your game. Cleanly made, top-down, gridded maps, that are detailed and tell a story by themselves.
My only complaints - proofreading. I really do understand how easy it is to miss bad grammar and spellings, even after proofreading your work multiple times, but there's still glaring mistakes that pop out here and there. It's true, it may just be me, and it probably won't bother most people, but it's these little hiccups that prevent them from being truly polished writing.
But what are you doing here for good fiction? Buy this pack, and all the rest, because they have all the crunchy goodness you need to run some great zomb-apoc games.
