The third XCOM: Enemy Unknown patch is now live on consoles and PC.
According to developer Firaxis, the update fixes "a couple major issues including the AI teleport bug and the defeat screen when beating the game".
It also introduces recently announced XCOM: Enemy Unknown DLC in the form of Second Wave, which unlocks a range of post-game modifications. There are 16 in total, four of which are only accessible after completing the game on Impossible Mode.
In our XCOM: Enemy Unknown review we called the title a "surprisingly personal turn-based masterpiece" that "harks back to the golden era of strategy games".
