IGN: It happened. It finally happened. After months of near-begging, Valve has seen fit to let IGN into the Dota 2 beta. If you're unfamiliar with DotA, it originated as a mod for Warcraft III. It pits two teams of five players against each other, with each player controlling a single powerful hero unit. The goal is to push into your enemy's base and destroy their central structure, but to do that you need to take down a series of turrets that guard the three roads (or lanes) into the base. Players level up and grow stronger by killing "creeps," and can customize how they play by buying gear with money earned within each game.
