In Minecraft Tower Defense, your job is to protect your base and fight the monsters that are trying to get to your tower.
You must first make a winding road to your defensive tower so that you can get ready for the hordes of monsters that are coming. After this, you can build many types of defense towers and traps, such as towers that throw eggs, pools of water, and shooter towers, to name a few. The creatures will be pushed back by your defense network, and for every monster you kill, you'll get more resources. Between waves, you can improve your towers and traps and add more ways to defend yourself.
Have fun and good luck!
