Hard Truck Apocalypse: Rise of the Clans E3 Preview

GameSpot has dished up an E3 preview of Buka Entertainment's upcoming Hard Truck Apocalypse: Rise of the Clans expansion pack. Here's a bit to get you started:
This expansion pack will offer a brand-new campaign with up to 20 hours of new gameplay. Rise of the Clans will also offer a new quest system to players, which will include different types of gameplay, like timed missions, fetch quests, and racing. Some technical improvements have been made to the game engine, such as with the lighting. Night missions will look more dynamic, because headlights and use of flares will come into play after dark. Location-based damage has also been introduced, which will allow you to try to shoot out tires, knock out weapon mounts, and even shoot directly at fuel tanks and cabins for critical damage.

They've also posted quite a few new screenshots depicting some of the new areas in the expansion.
