How to unlock the Micro SMG achievement in Hillbilly Doomsday - Definitive Guide
This is a decent enough rapid fire gun, fires in a tight spread pattern, and it costs $1000. You get to the shop after each boss. You can also quit out after getting the achievement and reload your save to get the money back if you so wish.
