It removes crafting, adds blood, guns, looting for food and guns (although I'm not sure if there are more than just one gun atm), zombies spawn in daytime, random chests spawned across generating chunks with loot in them.
My only problem is finding a map that was made for it.Found one in the thread:

If there is enough demand for it, that is and if people would post on this thread

We would need a way for structures to be generated or already built, and some way to refill chests periodically with random equipment from the mod like they do in the survival games servers.
