At this rate, we'll be playing a leaked build of Duke Nukem Forever by the end of the week. The onslaught of media hitting the internet in the wake of 3D Realms' closure continues, with this animation demo reel constituting the real crown jewel of the collection. There's honest-to-goodness gameplay footage in here, giving the best idea so far of how the game would have played.
Responding to orders Duke heads to Hoover Dam in an EDF Drop Ship to investigate a wormhole in the sky which is believed to be a portal from the Alien world. The Dam top is overrun with Alien forces so Duke is dropped off nearby and must drive his monster truck with a mounted missile launcher to make his way to the to the Dam.
