Anyone can buy their way into the Dota 2 beta right now, but it can be awfully confusing to choose from the dozens of heroes when you're just starting out.
That's where we come in. This roster rolodex gives you a snapshot of every hero in the game, including their abilities, best roles, and most importantly, how difficult they are to master. If you're unsure of which Radiant or Dire hero will best suit your playstyle, this is the best way to find out. You'll also find a glossary below, to bring you up to speed or refresh your memory on what some of Dota 2's key terms mean. Once you've seen what every hero is capable of, you'll be that much more prepared for what awaits on the fields of battle."
