In Zombie Last Castle 3, humanity needs your help to defend the last place where civilization is still alive.
Start by choosing the number of players and difficulty. If you are playing by yourself and this is your first time, you should start with ease. You have all kinds of weapons one might need to kill zombies, but it takes time, skill, and gold to unlock and develop them. You can choose from different kinds of guns, so be careful what you shoot. Also, don't shoot the doctors who are trying to heal your castle. You can improve your lasers, bombs, missiles, and traps. Collect medical kits, ammunition, and new guns to stay alive through 10 waves. Move up and down not to miss flying enemies.
Have fun and good luck!
