Play as a gun-wielding granny who must contend with an army of snowmen in this quirky defense game. Shoot snow enemies to prevent them from destroying your cabin, running away, or killing you. Stand near plants to water them and collect their seeds, which refill your ammo. Move to highlighted spots to build structures that will distract or deal damage to snowmen. When you kill an enemy, you gain experience points. Collect coins from fallen enemies, crates and treasure chests. You also gain experience points and money by completing objectives. Experience points are used to improve your skills and money is used to buy upgrades.
