My horde base and my loot/heat base are the same thing. I haven't done that in a long time and it turns out that hoard nights are more fun for me now, as I have to do something to protect my loot!
Defending a base that covers the entire limits of a claim block in SP required some thought but I would say its the strongest fortress I've ever built. Building it, however, was almost too much effort for one player, but its amazing what one can do when he's a stubborn son-of-a-gun! Isn't that right, MM? 😉
Edit: Also, there is no cheese or exploits, unless using the tendancy of zombies trying to get closer to the player is one. But no zombie ramps, pits, or even spikes!
