Remember me mentioning three Downloadable Content coming to New Vegas? no? well here's the first and they released a trailer for us to consume.
An expedition into the unspoiled wilderness of Utah's Zion National Park goes horribly wrong when your caravan is ambushed by a tribal raiding band. As you try to find a way back to the Mojave you become embroiled in a war between tribes and a conflict between a New Canaanite missionary and the mysterious Burned Man. In Honest Hearts, the decisions you make will determine the fate of Zion.
New terrain, new enemies, new weapons and perks are what to expect in Honest Hearts. It comes out on May 17 and if your interested to make your Fallout game much longer you'll have to cough up $9 or 800 Microsoft points.
Old World Blues is up next and will be out on June, after that will be Lonesome Road coming out on July. These DLC's will be released on PlayStation 3, PC and Xbox 360 simultaneously this time.
