So not sure about this but I may include a class that uses a melee weapon as their main thing but Im not so sure how it'd work ingame.
You;d p much be responsible for building defensive structures like walls, towers, bunkers, etc, and running around with a sledgehammer or something, but I may just give them a pistol or something else.
If anyone has ideas for some sort of running around scrappy build defensive stuff guy Im all ears.
