While the classes don't stray too far from MMORPG norms, it's nonetheless instructive to see exactly what the game has in store. First up is the Gladiator, who, as you might surmise, exists to do massive melee damage at close range. The Soldier is your basic tank archetype, responsible for juggling aggro and taking a beating for his friends. The Mystic is Gods & Heroes' answer to ranged DPS, while the Priest is, crazily enough, the main healer.
You can get a full rundown on Gladiators, Soldiers, Priests, and Mystics at the game's main website, and don't forget to check out the new screens below.
