with every army mnl amasses, you can assure he is going to try to take over the world, not even his friends are safe, so some survivors decided to try to keep them away from their base. (but its also kinda stupidly inconvenient they decided to have the enterance be a gaping hole.) this is my first ay defending, so don't expect it to be the best, but custom mnls are pretty easy to add.
