Mark your calendars: The Dragon Age 2 demo is coming to the PC, Xbox 360 and PlayStation 3 on Feb. 22! Not only will the demo give you a sneak peek at this action RPG, but playing it will also give you a special weapon in the full game. Here are the details straight from BioWare:

"In the demo, players will venture through the game's prologue, choosing from three different character classes. They'll also learn more about Hawke and hone their skills and abilities that will make them the ultimate hero. After finishing the prologue, players will enter a key new location in the world of Dragon Age, Kirkwall, befriending Isabela, a romantic interest in the game who is also a deadly smuggler. Upon completion of the demo, players will unlock a special weapon, Hayder's Razor, an ancient dwarven blade which increases health, mana, and combat abilities, in the full release of Dragon Age 2."

The Hayder's Razor offer expires on May 31. Dragon Age 2 is scheduled to launch on March 8 in North America and on March 11 in Europe. For more details on the game, check out our hands-on preview and our interviews with Executive Producer Mark Darrah and Lead Writer David Gaider.
