Dragon Age 2 is the latest fantasy RPG from the folks at Bioware, and if you're watching this video you've probably either just gotten it or are thinking about it. Check out the vid for a walkthrough of the prologue quest, Destruction of Lothering.
From the Creator:
1. There are two tiers of special abilities, access the second by holding the RT button while in battle.
2. When fighting the Ogre, run behind him for a safer attack.
3. Alternate between attacking the Ogre and Darkspawn. The Darkspawn will quickly overwhelm the player if they are left unattended.
