Sledgehammer
The argument
Short answer
Base walls, gates, a very loud no. Slow and honest.
Also: sledge
How it works
Sledges exist to undo building. They are not quiet. They are not fast.
What to do
Bring friends if you mean a wall. See offline-raid.
Don't
Don't swing it at a freshie as a personality.
