With the PC gaming community set aback by Crytek's Crysis demo (to be released a month from now), CEO Cervat Yerli took the time to talk with IGN about two of the most notable alien levels, Ice and Core. These two levels introduce a feature often talked about in Crytek's previous interviews: zero-G navigation and subzero temperatures.

Without giving too much details here, Crysis' technology offers not only graphical attraction and physics, but also adaptive AI. Thinking up strategies is often the norm with experienced first-person shooter gamers, so the inclusion of copy-cats might bake your temper to a roast. Alien Troopers, after observing your own tactics used against them, will adopt those as their own and try each one against you. With tentacles. Ten fold.

But without further adieu, we present you with the video interview embedded below. It's actually high definition in IGN's site, but for all purposes of bandwidth to our other readers, this one's a lower quality version. View and be enlightened. Crysis ships worldwide, thanks to Electronic Arts' worldwide distribution access, to capable PCs on November 16, 2007.
