Firaxis' XCOM: Enemy Unknown could be getting a dose of DLC treatment, if the recently uncovered Steam achievement clues are right on the money. "Confounding Light," "Deluge," "Friends in Low Places," "Gangplank," "Portent," and "Furies" are the achievements listed that may refer to new missions which are not part of the base game. These hints could very well be a sign of even more XCOM content to come, which should further expand the horizons of an already well-received title. The devs have remained quiet on the DLC front so far, so these are assumptions for the meantime.
PC gamers enjoying the turn-based joys of eliminating aliens in XCOM: Enemy Unknown may have encountered a few annoying bugs other than the extra-terrestrial variety, though. The glitches include movies rendering in 720p and not in full HD, ammo depleting noticeably faster when using rapid fire, and floating hair pieces, among others. Firaxis has fortunately remedied these with a recent Steam patch, so anyone playing XCOM: Enemy Unknown should now have a better PC gaming experience.
