An ambitious and heavily-featured game of grand strategy. Teams first select one of four factions (Elves, Orcs, Creeps, Undead) which each have their own armies and hero pools. They then battle on one of five maps of wildly varying sizes, each with different objectives.

Players can destroy and rebuild outposts, construct towers and fortify their bases, reinforce specific lanes with extra troops, or re-route lanes to different locations. The heroes each have six abilities which can be empowered with a range of talents, while upgradable items can shore up weaknesses or bolster their strengths.

EotA: Twilight shares a universe with two other games: a co-op survival called EotA: Exodus and a team escape called EotA: Maze.
