How to play?
As I said, turrets replaced by iron and snow golems. You can built turrets the same way as you built golems. The screenshot is below. For first structure, you use iron blocks and pumpkin on a head, and for second structure, you will use snow blocks and pumpkin on a head.
If you will built turrets near you and some hostile mobs will be close to you, then turrets will attack them.
