Reader Willkiller tipped us to this WTF?!-thread in the Gametrailers forum. In GTA IV multiplayer, apparently someone's turned into a zombie wearing nothing but yellow Rockstar-logo underpants.

There are a few comments indicating gamers have seen zombies in online play, but nothing about transforming into one yet. Theories range from getting killed by a Rockstar employee, to killing a Rockstar employee, to getting the highest ranking.

They quote the official strategy guide (I don't have it) "If you see unclothed characters, look out! Only players who have reached the max ranking of 10 and a few other "special" people get the honor of shooting in their skivvies." But this player says he's only at Level 2. The user's name in the forums is GTA. I couldn't find a PSN ID for him.

More pictures after the jump. Warning, one's at a kinda uncomfortable low angle.

Did your children get an Xbox 360 for Christmas? Are they already bored of the two or three games you already bought them? Of course they are. They are children. They have the attention span of a gnat on speed. Well as we mentioned on Friday, 800 Microsoft points today earns you at least another hour of peace and quiet as your children work their way through SpongeBob SquarePants Underpants Slam! Available for download right now, it'll bring your children minutes of side-scrolling slapstick goodness, allowing you to take a moment to reflect over the holiday - at least until they start beating each other with the controllers. Ah, to be young and covered with self-inflicted bruises again.
