Quite a good old school feel about it.
I can see the similarities between Chill & Rotworld (obviously using the same engine).
Strangely, I understood the basic mechanics reading Chill (first time round), but it took a few readings before getting the 'gist' with Rotworld. Don't know why.
The outlay is obviously different, but both work rather well.
The artwork is pretty good.
The sections on the causes of zombification (zombology), and using paranormal talents are good.
It's well packed (65 pages) with info on zombie survival, radiation, poison, etc.
At the mere price of £3.13, it's a bargain!
A must buy!
