i love the Fate and Event cards from this Game, where you draw a card and it tells you how the Game Progresses ...positive and negative.
Moving enemys, survivors getting ill, military incoming, more zombies, such things.
So i am searching for Games with this mechanic.
I Think arkham horror has such an mechanic for example.
If it's alright only to have event cards and not fate cards, then the other games in the States of Siege series might work for you.
Nemo's War, Darkest Night, Astra Titanus, and Legendary Encounters: Aliens could also be worth checking out.
A lighter one could be Deep Space D6.
