Currently I have 2 horde ready bases, One better than the other. My current base is in the desert biome, which allows me to have direct access to shale (gas) and many other resources. As I seek to peak out the capabilities of the world (bases and player), I am trying to start a base that is at the intersection of 3 of the 4 biomes (https://7daystodie.fandom.com/wiki/Biome) . The wasteland was the key for building the horde defending portion of the base. This will maximize the difficulty experience and loot during horde night. The desert will continue to give me access to much needed resources. The forest biome just happened to be at the convenient intersection of at least 3 biomes. I will likely have that be the nice area of the base that has a fun/chill vibe, including drawbridges for vehicles, and a helicopter landing area.
