Action-oriented game in which players pick a tag-team of two heroes, and collect points that enable them to transform into titans.

The original 'DotA 2'. It has a large battlefield with distinct towns to capture: each contributing different lane troops and selling its own items.

Light-hearted game that experimented with lots of gimmicky mechanics and unusual heroes. The battlefield has bridges which can be raised and lowered using levers to block and open paths.

Heroes can engage in optional side quests, or pick up one of several sub-categories of items which have unusual rules. There are also modest army-customisation options, as well as a selection of powerful tower upgrades.

All heroes are designed to use and interact with 'conditions', a fixed set of debuffs that can be manipulated in complex ways.

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.
