First raid attack on Taffington Boathouse by super mutants, I chose that settlement to be my main base (I love the water). The only thing that saved my settlement and all of my settlers was the wall I built, it completely blocked access to the settlement even behind the boat shack. If the wall wasn’t there all my settlers would have died and my settlement would have been destroyed (i clearly underestimated raids). The super mutants actually doomed there selves by destroying the generator that connected to the powered door, the only way through the wall, and luckily I built a big bed room for me over top the house so I was able to snipe them all (they had surprisingly good aim). I have a mod that get rids of the build limit and another mod that makes raids more common (I loved the rush of that raid).
