There was an interview about Turok on this week's Major Nelson podcast. Kimono Dragons and Insectasoids aside... sounds pretty weak. It sounds like they're making a generic FPS but shoehorning a lot of conventions in there... alternate fire modes for each weapon, "stealth" aspects, multiple approaches to the same situation... Remember, this is the same team that thought having an achievement for teamkilling would be a good idea.
The only cool part is that during multiplayer there will be NPC dinosaurs that will attack anything and will respond to noises and light and stuff, so you can lure them toward your enemy.
