The viral campaign for next summer's Man of Steel appears to have officially launched with The DSRW Project, an ARG that purports to research deep space radio waves.

All day, fans have been hard at work decoding incoming signals that bear more than a passing resemblance to Kryptonian characters, ultimately revealing a secret site that appears to offer some form of extraterrestrial countdown. What it's counting down to, however, remains to be seen.

Last year, Warner Bros. debuted a similarly SETI-inspired viral site for Green Lantern, another DC Comics property.

Directed by Zack Snyder, Man of Steel stars Henry Cavill, Amy Adams, Michael Shannon, Laurence Fishburne, Diane Lane, Kevin Costner, Antje Traue, Ayelet Zurer, Russell Crowe, Harry Lennix and Christopher Meloni. It arrives in theaters everywhere June 14, 2013.
