PixelJunk Monsters Android Game Description:
The gameplay is a classic funny Tower Defense. The locations are designed as natural landscapes with paths for mobs to attack the player. The towers that the player must place on the sides of the paths are designed with a medieval flavor. Mobs are strange monsters.
Attacks on towers occur both from the ground and from the air, so you need to combine different towers to provide sufficient defense. Immediately after killing a mob, the player is rewarded for it with gold coins, for which he can build new towers. Also, there are cards with which existing structures can be upgraded.
