Yesterday, I received irrefutable photographic evidence delivered to my doorstep that proves my home has been destroyed in the opening salvo of a war against space invaders. Photos don’t lie, so it’s obviously too late for me. but you can still save yourself by enlisting in W.A.T.C.H.

The “largest UFO intelligence organization that assesses planetary threats of extraterrestrial origin,” W.A.T.C.H. is featured in the upcoming movie Battle: Los Angeles, starring Why So Serious veteran Aaron Eckhart. You can join the fight by checking in to the game’s Facebook app using Facebook Places for a “battle,” with the next fight scheduled for Miami on February 23rd, between 12PM and 3PM EST. Alternatively, by exploring the movie’s viral content at websites like ReportThreats.org and UnidentifiedEnemy.com, you find classified (and heavily redacted) documents, video interviews with alien experts, eyewitness testimonials, and intelligence files detailing the alien invasion. While these files don’t call for much interaction, they do offer a fairly comprehensive preview of the film’s alien antagonists. Six Special Ops missions in the viral campaign’s Facebook app involve sifting through this information.

Surviving battles and completing Special Ops increases your W.A.T.C.H. rank and unlocks exclusive wallpapers, photos, and videos relating to Battle: Los Angeles and its March 11th release. Complete enough tasks, and you can be entered for a chance to win prizes, such as a PlayStation 3 system, Blu-Ray Disc Players, and Sony gift cards.

I’ve been told to “look closely” at the Battle: LA W.A.T.C.H. Ops poster, so there may be more to this campaign. MovieViral has extensive coverage of the campaign’s progress to date.
