Last Zombie Defense has an infinite number of levels, and each level gives you a new set of problems to solve. Complete all of the levels to be the best survivor.
In Castle Defender Saga, it's up to you to lead the defenses of a castle. Before each round, you set up your defensive plan, hit play, and then watch your units fight against waves of enemies that get stronger and stronger. Just as the fight starts, you'll have the chance to watch a short ad that will make your defenses much stronger.
You will get gold coins for every round you play. You can buy new units to put on your castle with this currency. There are mages, knights, bombermen, and summoners in these units.
You can improve every part of your defensive strategy. You can add more archers and boost the health of your castle. But each unit can also be upgraded on its own. When you've upgraded a unit 10 times, you can use mana to promote it. This gives your fighter a lot more power.
Have fun and good luck!
