The greatest team-up title of all time is back! A proud DC tradition is restored as writer Mark Waid (52, SUPERGIRL AND THE LEGION OF SUPER-HEROES) and legendary artists George Perez (THE NEW TEEN TITANS, CRISIS ON INFINITE EARTHS) and Bob Wiacek (ORION) put Batman and Green Lantern on the trail of what could be the greatest weapon in the DCU!

The trail leads to Ventura, the gambling planet...wanna bet what'll happen if they don't get their hands on the weapon?
