It's the two-year anniversary of the free-to-play ARPG Marvel Heroes today, and that calls for a celebration! The game is releasing its 48th playable hero today, Dr. Doom. Doom is essentially painted as the main villain throughout the campaign of the game, so releasing him as a playable character is a pretty big deal. He has a variety of specializations, including the ability to summon Doombots to aid him in battle.
The Thing is also getting completely reworked. He was one of the original playable characters, and it shows through his gameplay. He's a straight up "big guy" fighter with nothing very interesting in the way of mechanics. Evidently the developers agree, since they're reworking how he plays. They're even including the ability to summon the Yancy Street Gang wearing Thing masks!
Most importantly, all players can play any character up to level 10, for free. Well, except for Dr. Doom, he's off limits. At the moment, this seems to be a limited time idea to celebrate the anniversary. They even pose the question to themselves of "How long can we keep this up? and answer themselves with "How long would you like us to? ..."
