I can imagine when pipe weapon come, blunderbuss will be forgotten and nobody use it. However I never expected the A20 just delete it. For now , pipe shotgun is weaker than blunderbuss, it have low damage and hard to knock down zombie. However forget the game data, blunderbuss have powerful sound and firelight. And the bullet can be handmade,and it is very conform for wasterland style. I‘m very like this gun.
And no matter how, add new weapon or zombie or building or anything are always better. Delete game content is no interesting.
