Published and developed by Perfect World Entertainment, the same team that brought you Perfect World and Rusty Hearts, Battle of the Immortals is a free to play MMORPG including an array of exciting features and mechanics.

Battle of the Immortals features 5 unique classes including Champion, Berzerker, Heretic, Magus and Slayer, all of which have their own unique appearance and abilities. Each class has access to over 20 different abilities and skills, learning at least 2 abilities every 15 levels, up to the level cap which currently sits at level 115.

The pet system in BOI is in-depth compared to most, your pets are not mere companions that travel around with you, they can battle, evolve, learn new abilities and increase their stats. To catch a pet a player must slay a certain number of the monster they hope to acquire, after a while and if they're lucky, a friendly version of that monster will appear and offer its services. The player can then choose to recruit the pet, giving them the option of summoning it at any time. Pets grow naturally alongside the player but they can also be improved via other means such as merging with another pet, being reincarnated or using the pet boost system.

The questing system is highly user-friendly, you will fly through quests in a matter of minutes thanks to the auto-locate feature. Whenever a quest is on your tracker, you simply click the NPC, Object or Mob of interest and it will walk you straight there, removing the chances of getting lost or frustrated on a quest. To help even more is the XP Combat Ability, as you complete quests or kill monsters and earn a certain amount of experience points, you can unleash a deadly attack which can kill 10-15 of almost any even leveled monster, making the kill X amount quests a total breeze.
