I did this one a few months back, when the Countdown preview showed up in Wizard, and never got around to posting it.
I figured I'd better post it now since Infinate Crisis has started. Although God help me, I don't think I'm going to be able to make heads or tales of that story without a DC Universe reference guide handy.
I'm all for referencing continuity, but I'm getting a bit lost. (Mind you, I rather liked Countdown)
