Technically S2 Games' upcoming multiplayer action-RTS game Heroes of Newerth has been in closed beta for quite some time. However today the developer has decided to open the flood gates and let anyone sign up to play their game, which is blatantly inspired by Defense of the Ancients.

The open beta registration has a small catch. It's only available to the public until the end of the day on Christmas Day. While the web site is also taking both gift and personal purchases of the full game for $30, there's still no word on when Heroes of Newerth will come out of its beta state and actually become a commercial title.
