Firaxis will soon be beaming down a patch for XCOM: Enemy Unknown. The update should fix a number of issues, notably "abductor roof visibility problems," one of the game's more annoying headaches. Inaccessible SHIVs should also be addressed. A number of other fixes will be made as well, including better multiplayer connectivity and solutions for certain states that would make the game hang.
And some good news for XCOM beginners: Easy difficulty will be made easier. Also of note, the patch will not address an issue where players who beat the game are greeted by a defeat screen. Firaxis is aware of the issue and looking into it.
