2K Games hosted a video livestream of its booth shortly after the re-announcement (or is it un-cancellation?) of Duke Nukem Forever, showing off a few fans getting their first shot at the alien-murdering sim. You can check out a couple of over-the-shoulder gameplay clips from this stream posted just after the jump.
And, yes, it is worth noting that this particular demo begins with Duke Nukem relieving himself, an action you apparently execute by pressing Right Trigger. You're going to feel tempted to press Left Trigger, but for the sweet love of God, you have to resist that urge.
