City of Eternals is a massively multiplayer online role playing game (MMORPG) with a vampire theme.
In the game players take up the role of a character that has just been bitten by a vampire. At the start the player will have limited abilities and generally a weak character, but in traditional RPG fashion the player will earn experience and slowly level up. New levels unlock new abilities and improved stats. The player can move his avatar around a large city called New Valencia freely. In the city the player can interact with NPCs, enemies and other players in real-time. NPCs will provide the player with quests and defeated enemies will yield experience points and loot. The avatar can also be equipped with items (including weapons and apparel) that boost stats.
Each player has its own home which can be decorated with new furniture. Various items can also be bought using in-game money at stores in the city or using real money through micro-transactions.
Players can band together and (in contrast with other Facebook) games there are extensive chat option within the game.
