The latest update for DOTA 2's beta now delivers a "Least Played" mode, which will match players who are forced to use characters other the 20 that have given them the most wins. It's meant to get players in the game's closed beta to explore the game's full roster, which now runs 96 character deep.
"Least Played" enforces the top-20 restriction on all sides, so everyone is playing outside of his or her comfort zone, too. "Having an even playing field for everyone in the match will hopefully encourage players to break out of their comfort zone and try new heroes," Valve said on the Dota blog.
More than 3 million are currently participating in the beta; the post said that DOTA 2 has seen more than 100,000 games played so far.
