About Rise of the Zombies!, from BoardGameGeek:
In Rise of the Zombies, a fast-paced card game of zombie survival, players play Location cards to form a path from the Safe House to the Rescue Helicopter, while fighting off hordes of zombies. The players must also play fast because they are racing a real-world timer. If time expires, the Survivors are left behind and die.
Players play cards during a common "Survivor Turn". At the start of the Survivor Turn, all players can discard and draw until the number of cards in their hands is equal to their Hand Sizes. There are no player turns. Declare what you are doing, which card you are playing, and which zombie you are attacking, and roll dice. This simulates the chaos of combat. Most cards can be used to perform more than one function. You can perform as many actions during the Survivor Turn as your cards can support. You can even trade weapons and items with other Survivors in your Location.
Once all players have resolved their actions, the Zombies get to attack.
The game is co-opish... how you play the game is up to you. You don't gain anything by having other Survivors die, but if you spend too much time trying to help others, it might cost you your own survival.
Help them? Leave them behind? It's all up to you.
