Battle of the Immortals was a free-to-play massively multiplayer online role-playing game (MMORPG) by Perfect World Entertainment.

[6] The central gameplay consists of completing quests by NPCs (non-player characters) and hunting monsters to gain experience, which can level a player up and obtain and use better gear in the game.

The game is free to download and play, with an optional in-game cash shop that can be used to purchase items to help assist the player in leveling faster or getting better gear.

Armor and weapons can be collected as drops from monsters ingame, as well as being purchased from other players who sell their wares.

Each of the five classes have different abilities, so picking the right equipment is essential (a spellcaster will be considerably weakened by using a blade, and the same applies to melee fighters who use a staff.)

This helps the player avoid expensive costs of having to remove all the stats in their previous gear and having to redo every piece of armor each time they hit a level gap.

Primal Gear is also newly introduced, giving soul gear-like properties with additional combat-related benefits (more damage per attack or higher defense.)

Pets can be caught by fighting monsters or using items from the Cash Shop and buying them from an in-game merchant.

Items included in the cash shop can either be used as cosmetic (used to change the look of your avatar), upgrades (gems to help improve your gear or pets), and functionality (warcries, which can shout to everyone who is logged into the game server at the time).
