When crowds of zombies approach your castle, there are two ways: run and hide, or arrange a noble brawl under the walls. For example, play bowling in the game Bowling vs Zombies Factory 3D, but use a cannonball instead of a ball, and the walking dead instead of skittles. With each new level, there will be more zombies and they will be faster, so collect the reward and get stronger, buy more guns and improve them. At every second level, a boss is waiting for you, so you should save resources for fights with him. By killing them, you can get up to ten skins for your weapons, which will add a range of features and help you win in Bowling vs Zombies Factory 3D.
