1) resources in the deadzone are so hard to find especially the wood, it would be nice if there are specific raids for collecting wood, cloth or steel.
Sawmill, for wood
Textile factory, tailoring for cloth
Junkyard, blacksmith house for steel
2) everybody needs a pet, what if we can raid zoo or pet shop and own some pets(specifically dogs).
-Dog would bark and increase the percentage of horde.
-Pet can only take down a single zombie kill it for an given amount of time example is ten seconds and pets are vulnerable in that time while they attack a zombie.
3) flamethrower and Molotov should also be available. it will damage per second and can block zombies path for a small radius
