Castle Defense Online

Castle Defense Online is a fun 2D strategy game in the subgenre of tower defense (or, in this case, castle defense) where you play as a warrior determined to protect a gem kept in the castle.

Gameplay in Castle Defense Online is as follows: your warrior starts with a big sword and two special attacks. With these methods of defense, you'll have to prevent waves of enemies from destroying the gem stored in the castle's basement. The enemies will emerge from both sides of the screen, so you'll have to keep moving to prevent them from reaching the gem.

In the first few levels of Castle Defense Online, the enemies are fairly weak, and their weapons don't inflict much damage. However, as you level up, archers, mages, catapults, and more will get added to the mix, and your enemies will be harder to kill. On the other hand, you'll have to defeat the boss waiting at the end of each round in order to advance to the next level. At the top of the castle, there's a merchant you can buy special weapons and attacks from, which you can then use to defeat your most powerful enemies.

Castle Defense Online is a fast-paced and fun castle defense game with clean and visually appealing graphics where you can spend some time killing goblins.
