Sooooo, umm, Mongul killed Batman? Straight up hole through his chest dead. All this, while Jimmy Olsen and the rest of the "gamers" watch on in amazement, thinking this is the greatest game ever, but Toymaster is freaking out, trying to tell them it's real.
Of course, Mongul's arrival on Earth doesn't go unnoticed by Superman, who shows up shortly after, and isn't too optimistic about the vital signs (none) he's getting from Bruce, but has to fight off Mongul either way. While fighting Mongul, Clark feels there's something wrong with him, he's angry, and he has to actively fight off the urge to kill Mongul. So instead of killing Mongul, he does the next best thing and punches him 200 miles away, into the ocean, then goes to check on Bruce.
Yep, still dead. But then something happens, the nano machines, or whatever, that are controlling and creating this game take a hole, and resurrect Bruce, giving him all sorts of powers, so naturally, the three people playing the game try to use them to attack Superman, but that all comes to an end when Clark addresses Jimmy directly. So, Jimmy realizes this is real, and sort of freaks out a bit. Everyone's attention turns to Toymaster's engineer, Agnes, who is actually some crystal boned alien, who has the machine controlling the "game." Bruce tries to destroy the machine, but Clark stops him, saying if he does, it could mean the end of him as well.
By this point, Mongul is back, and he's attacking Gotham, so Clark throws super powered Bruce into action, and goes for round two with Mongul. Unfortunately for them both, Agnes takes the "game" out of beta, and launches it to the world with the help of whatever those spores that were spread last issue. With the worlds gamer's logging on, they create a hive mind which takes control of Bruce, and uses him to attack Clark, keeping him away from Mongul who is ready to take over Earth.
