Batman, Robin, Deathstroke Shadow War crossover concludes in May with a bang ... and Prometheus

gamesradar.com:

Writer Joshua Williamson's three-title 'Shadow War' crossover between the monthly Batman, Deathstroke Inc., and Robin series continues and concludes in May with the final chapters, along with two specials putting a bow on the aftermath of the assassination of classic (and great!) Batman supervillain Ra's al Ghul.

The action continues in May 3's Batman #123 drawn by Howard Porter prominently featuring (as you can see by the cover art above) one of DC's most dangerous villains of all time - Prometheus - along with the long-awaited father-son reunion of the Caper Crusader and the Boy Wonder. 

All that and a cliffhanger. 

Plus Williamson writes a backup story drawn by Trevor Hairsine showing what happens when Slade Wilson is infected with Joker's toxin.

The action continues three weeks later May 24's Deathstroke, Inc. #9 and Robin #14.

in Deathstroke, Inc. drawn by Paolo Pantelena, a "tragic death" escalates the Shadow War. We're gonna assume this means another death and not just Ra's' so it looks like the body count will rise.

Then in Robin, drawn by Roger Cruz and Norm Rapmund, it's a three-way fight in this three-way crossover between Batman Inc., the League of Shadows, and the Secret Society and it looks like Robin will reveal the truth of who really killed Ra's. 

Then on May 31, the whole shebang wraps up in Shadow War: Omega #1, the 48-page one-shot special written by Williamson (who else?) with art by Stephen Segovia and covers by Jonboy Meters, Mikel Janin, and James Stokoe. 

According to DC, there's been a  real "mastermind" behind 'Shadow War' (early, wild guess ... Ra's himself?) and Batman and Robin must team to put a stop to their plans.

Plus Shadow War: Omega #1 leads into DC's next big summer event. Whether
