IGN previews Raven's hacked up Q2/Heretic 2 engine based Soldier of Fortune. Here's an excerpt:

The result of this mixture of minds is a title that falls pretty squarely between the extremes of Rainbow Six and Quake 2. From a very standard first person point of view, you run through level after level shooting just about anything that moves. In addition to shooting or stabbing the enemy with your 12 different weapons, you will be able to duck, crawl, lie prone and lean around corners. "The object is to simulate firefights in the real world where people duck and run for cover," says John Tam, the associate producer on the project, "we want this to be a lot like an action movie."
