The Xbox LIVE House Party is about a month away and will be similar to the Summer of Arcade promotion having one new title released per week.  Beginning February 15, four titles (headlined by Alan Wake’s American Nightmare) will be released.  Much like the Summer of Arcade, purchasers of all four games will be rewarded with 800 Microsoft points.  Below are the four titles along with details and a brief summary of each one.

• Alan Wake’s American Nightmare – In this brand-new stand-alone experience, Alan Wake fights the herald of darkness, the evil Mr. Scratch. A thrilling new storyline, hordes of creepy enemies, serious firepower and beautiful Arizona locations, combined with a fun and challenging new game mode, make this a must for Alan Wake veterans, and the perfect jumping-on point for new players. Can you survive until sunrise?

• I Am Alive – One year after a worldwide cataclysmic event has wiped out most of human civilization, a man struggles for survival. Faced with an insecure, decaying and hazardous world, he scours a desolated city, searching for his long-lost wife and daughter. Survive the suffocating, murky streets covered in dust. Climb the teetering remains of last-standing skyscrapers to reach breathable air and find untouched resources. Explore the crumbling ruins of a once-thriving metropolis. Discover a changed human condition, punctuated by distrustful survivors, dangerous armed gangs and victims in need.

• Nexuiz – For centuries, the Kavussari and the Forsellians have waged war. They have a fragile truce but, because of their seething disgust of each other, still pit warriors against each other in arenas rather than on the fields of war. These episodes of lethal combat are broadcast throughout the galaxy as entertainment — a spectacle known as The Nexuiz Competition — an arena-based first-person shooter where you can alter the rules of the match and the laws of physics while dominating opponents in ever-changing hostile environments.

• Warp – A puzzle-based stealth action game where you play as Zero, a lovable-yet-lethal orange alien with a big score to settle! Captured by the villainous Commander and imprisoned in his underwater facility, Zero must plan his ultimate escape using his arsenal of alien abilities — warp, frag, echo, swap and launch.
