Trust me, I am not the Traitor.
For Orcs there is no other life but WAR!
1. Do the zombie players take full turns like heroes do? If so I should have been able to stack our deck with Shuffles before the other zombie player went and win the game.
See below. But on a side note if the zombie deck is every empty it is reshuffled immediately. Also note that each zombie players hand size in a 2 ZP game is only 2 each.
Just remember if the heroes deck ever runs out the zombie players win the game that deck is NOT reshuffled.
2. Or does the 2 zombie players pretty much just act as one? This seems stupid if that's the case. There would only be disadvantages to having 2 zombie players.
The 2 zombie players take turn sequences as would 1 zombie player. So if its the move zombies phase 1 player moves his zombies and then the next player moves his zombies before player 1 can move on to the next zombie phase.
The pro to having two zombie players is that normally you are allowed to discard 1 card before your draw step as a zombie player. With two zombie players each of the players gets to discard 1 card so you could potentially go through the zombie deck faster removing the cards which at the time are somewhat useless to helping you win your scenario.
3. Do play immediately cards get played before the zombie deck is shuffled?
Play immediately cards are played as soon as they are drawn and resolved.
