I played Axis & Allies & Zombies twice, but with two important caveats: 1. We only played with two players, 2. It was the first Axis & Allies for both of us. That said, my friend really hated the massive amount of randomness which led him to lose his attacking army (which doubled mine) on a massive raid on Moscow, leaving behind a next to defenseless Germany and a whole lot of zombies in the russian Capital. I really liked that event from a narrative view, and it’s not as it was an uncalculable risk, as I stocked Moscow with only infantry just for that purpose (only infantry units turn to zombies, and zombies attack attacker twice as often as defenders), but we’ll continue to play Twilight Struggle to quench our thirst for world domination. The long time it took to put all the units on the board at the start of the game didn’t help, but that was of course a detriment due to not playing with five players.
For a more objective criticism,the rules are not as clear or complete as I would have liked (as written, troops can’t be attacked by zombies when they are in areas belonging to one of their allies), and there are some production mistakes (spelling errors on the map, one card presumably missing (cards spawn zombies in every country except for the Balkans).
