Protecting their castle from a huge group of determined enemies is the most important thing players have to do in Cannons Blast 3D. You will need to use a heavy machine gun and a strong cannon to kill enemy units that are coming at you before they get too close. Remember that you only have so much ammo, and reloading takes time. As you earn more gems in the game, you can access two more deadly tools and improve the ones you already have.
In Cannons Blast 3D, you have to aim and kill enemy units that are coming to your castle before they get there. Pick carefully where to aim your fire, because you only have so much ammunition, and refilling takes a very long time. When you play defense well, you'll get gems that you can use to buy two more guns or improve the ones you already have. Heavy enemy units start to appear, making the game harder.
It's important to get good at timing your gun reloads in Cannons Blast 3D. Keep in mind that different enemies move at different speeds, so be smart about how you decide where to aim your fire by figuring out when each enemy will arrive. Also, use your earned gems wisely by choosing whether to buy new weapons or improve the ones you already have depending on how the game goes.
Have fun and good luck!
