Speaking with XCOM: Enemy Unknown producer Garth DeAngelis earlier this year, I managed to unearth a little information that had been (appropriately) unknown about the game at the time. Specifically, I learned that aerial combat is returning in Enemy Unknown. Dogfighting alien aircraft played a huge role in the original X-COM, a game that developer Firaxis is trying very hard to live up to.

But what other secrets are housed within Enemy Unknown? We've been privy to plenty of information when it comes to ground combat and tactics. Make no mistake, that's the meat of the XCOM experience, but the core gameplay of outwitting alien combatants is all supported by the structure of scientific research and aerial combat.

To uncover more pieces of Enemy Unknown's intricate design puzzle, DeAngelis has returned alongside designer Jake Solomon to exclusively explain to Joystiq about gunning down UFOs, scouring its wreckage, and turning its alien tech back against the invaders.
