You may have heard about DLC for RPG puzzler Might and Magic: Clash of Heroes being released on PSN and PC way back in September, but there’s been no word on an XBLA release. Until now that is. It seems that the I am the boss add-on sneaked its way onto XBLA last Wednesday for just 240 MSP. A free download is also available to allow gamers without the add-on to keep playing online with those who have the paid for DLC. I am the boss lets fans play as four new powerful bosses in Quick Battle and Multiplayer mode and brings 2 new achievements worth 20G to earn.
