Merge Wall Defense: heroes on the tower near the wall
In Merge Wall Defense you hold a castle against goblins, bats, ogres and bosses. This is one of strategy and management: buy heroes, place them on a wooden tower behind a wall and combine the same ones into stronger ones.
How to place the first heroes
First, buy fighters and place them on a wooden tower. Then drag two identical ones on top of each other to build one stronger. You place heroes on a tower and hold the wave, just like in Heroes Towers.
What changes after the fifth level
Each new fusion makes the hero bigger, faster and more dangerous. From the fifth level he still receives a second attack. This means that an early upgrade closes the gap faster, and a late upgrade gives more hits to one target.
