The game material is for the price plentiful and well designed (the second edition also includes maps with improved artwork). And as already mentioned here, you can buy more if need more zombies, and female and zombie dogs. The latter are meant for one of the extensions, but can be easily used with the basic game to spice up this little visually. There are even special "Glow in the dark" -Zombies, glow in the dark. :)
The weaknesses in the flow of the game, which is due to the rigid turn order without phase subdivision of the trains (each player performs all actions together with "his" zombie movements, then the next, etc.), which is just 5-6 players very in length can pull, until you get back to it. Action cards are indeed also played in the trains of the other players, but each player is limited to one card per underlying which are an ultimately not much to do outside the eigegen train. It helps mitzufiebern in the trains of the others with this and to see the whole as something played movie.
However, the rules of the game are so simple that you can implement house rules very easily without destroying the gameplay and balance. On the (English-language) website of the game there are also many optional rules to whole story scenarios and game modes.
Also worth mentioning is the ability for two players, whereby the sequence of moves will be shorter, but also the fun chaos of multiple, mutually stones or zombies that will be invisible in the way-laying players.
Overall, a good game for now and then in between. Etc. For weekly rounds however, it is a bit too uniform. With changing players and / or sufficient breaks between the evenings, however, an entertaining genre game with expansion potential.
