You can choose from a range of popular characters like Spider-Man, Batman, Superman and Ironman. You can then customize your character with different costumes that are available in the game.


The gameplay is very similar to the classic game “Kingdom Rush” where you have to protect your base by attacking enemies that come near it. You start off with just one hero but as you progress through the levels, you unlock more heroes to play with and explore different strategies for defeating the enemies.
