DMG,
to wit
Germany seemed weak on the water, and russia came at me with a stack 14 inf 2 arty which I couldnt assault on G1. If you do that, youre going to lose alot of german tanks and just create a crapload of zombys. So, i had to fall back and put a thin line of infantry on 3 more 2 value territories, which if i was russia, would have taken all of them R2 (8 ipc swing for 4x2 german losses) and set up to take norway forever on R3. Japan is quite strong w a big navy.
the combat dice for the main teams have a 6 for zombie kill. both teams can incendentally kill zombies while they fight each other, or when only fighting zombies, increase the hit chance (so say 1,2 and 6 %50 rather than 1,2 33%)
zomby dice are 1-2 attacker 3 defender 4-6 nothing, so zomby has a x2 chance of killing attackers than defenders, which overall retards the value of a relentless charge forwards
once all the defenders are dead, you can continue combat to eliminate all the zombies. you may not want to, bc you still take the territory and they deter the attack in later rounds as the attacker has to deal with them too
map size is fine, we needed a shorter game but its still pretty small on the order of classic. zombies may make the game more careful and drawn out since there are reasons to goof around and cleanse peripheral areas. 6 turn limit sounds fine but id think that 4 hours to a clear victor wouldnt be unreasonable. about 1 turn per hour until you get used to it. no quick and easy victories with all the new cards and techs.
