Castle Defense 2

Enemies attack your castle in waves. First, you will see weak foot soldiers, then tougher knights, and later mages and even dragons. In Castle Defense 2, you place towers along the road to stop them. The towers fire automatically, so your job is to place them wisely and upgrade them in time. If enemies break through the gates, the castle loses health. When its health drops to zero, you lose the level. As you defeat enemies, you earn gold, which you spend on new towers and on upgrading the ones you already have.

How to play?

Click an empty spot along the road, then choose a tower from the menu. Archer towers fire fast but deal low damage. Cannon towers hit hard but reload slowly. Magic towers cast area attacks that burn groups of enemies. For an effective tower defense strategy, place different types of towers next to each other. Archers mow down weak enemies, cannons finish off the tougher ones, and mages hit large crowds.

Upgrade your towers between waves. Click on a built tower and press the upgrade button. Damage goes up, the rate of fire increases, and the attack range becomes larger. An upgraded tower destroys enemies much faster than a basic one. Decide whether to build expensive, powerful towers or upgrade your older ones to the max.

Enemies get stronger with every wave. Fast runners will appear, and they are hard to hit. Bosses show up at the end of the level and have a lot of health, so focus all your towers on them. If you survive all the waves and the castle still stands, you move on to the next level with even stronger enemies. Fans of a classic tower defense game will find plenty of tactical challenges here.
