This suggests that this whole Enemy Within business is DLC for Firaxis critically acclaimed strategy reboot. We'll know more come 21st August when 2K officially spills the beans.
UPDATE: XCOM: Enemy Within - whatever it is - will be revealed later this month during Gamescom 2013, publisher 2K has confirmed to Eurogamer.
"We're looking forward to making an announcement on 21st August!" a spokesperson told us this morning.
A new slice of XCOM: Enemy Unknown DLC would be a welcome announcement - or it could be some form of mobile/tablet spin-off.
ORIGINAL STORY: Mysterious listings for something called XCOM: Enemy Within have appeared on the South Korean ratings board's website. (Thanks, CVG.)
Could this be a new game? DLC for XCOM: Enemy Unknown? A video series, perhaps? If only The Bureau actually existed to investigate this paranormal phenomena. Instead you have to settle for me, who's meekly sent an e-mail to publisher 2K politely requesting more information. And this is why I'm not as cool as Agent Mulder.
The last XCOM game, Enemy Unknown, was a rousing success. EG-contributor Rich Stanton totally dug it, as he explained in his XCOM: Enemy Unknown review. The critical darling was then ported to iOS last month for £13.99.
