We've received some tips indicating that Mr. Driller Online for XBLA is having a problem with the, er, "Online" portion of the gameplay. It seems that while the person hosting an online game is just fine, the connecting player can't drill anything. X3F put together a video of the bug, which we've placed after the break.
Another test of Mr. Driller's online capabilities was done today with the same broken result. No word on whether a patch is in the works. Best to save your 800 MS points for the moment, as there's no sense in supporting broken titles.
