I'm very stoned, but bear with me.
The map is a town a la resident evil or left 4 dead, etc.
Various shelters (territories) exist in the town where one can hide from the zombies and recruit ( bonus armies/) members.
There are alternating, two or three turn periods, where there are daylight hours, when it is safe to go outside and attack one another, and nighttime, when various tunnels will be fought over for control of the helipad (similar to those in king of the mountain) , which is in a fair location, somewhere. These tunnels can also be used for access to other regions and territories.
At nightfall, all units outside are automatically zombie food (nuked)
Zombies are an integral feature and, I find, there is just not enough of it in conquer club.
I mean, what video game takes itself seriously without a zombie mod of some kind, right?
