With the girlfriend out of town, an old friend-we'll call him, "K BROOKS" (gamertag)-came to visit this past weekend, and while there might have been intentions to explore the great cultural experiences that New York has to offer, our time together quickly devolved into several days of nonstop gaming. Over the past month, we'd been steadily making our way through PDZ's co-op campaign (online) and we were hoping to finish off the final boss first thing Saturday.
Since K BROOKS was unsure about packing his 360 for the train ride, I suggested he just bring the detachable HDD-he doesn't have a Memory Unit. I could transfer my profile & PDZ data from my HDD to my Memory Unit, plug his HDD into my console along with my Memory Unit, and then we could continue the campaign old school splitscreen styles. Wrong. PDZ data cannot be transferred between devices.
