the gatling gun was originally in the update for forts on the beta world, but it was removed from town gunsmiths. it had been available in the first level of the gunsmith. originally, the damage it could cause was 100-300, and could be bought for $30k. i don't remember the price changing, but i do remember the damage being increased to 220-360 or something similar to that. but right now, i doubt the stats it is introduced with will be the same as those i got from the beta world.
