Battleheart is an RPG with a simple idea. You need to take a crew of 4 warriors and try to survive a complete series of rising difficulty arena levels. The game puts players in command of a crew of up to 4 soldiers of diverse classes, like knights who engage themselves in melee, clerics having the power to heal, and wizards who do magic. Other than progressing, winning a level gains you experience that lets your crew learn new abilities and level up.
The game also lets you earn cash which you can use to buy armor, new soldiers, and weapons.
