As NWR left the Deadly Creatures demo at E3 2008, the word in their mind was "immersive", even though it was never uttered by the representatives showing the game. Deadly Creatures is a typical action game in some respects, but the story concepts and presentation are truly unique. You play alternative levels as either a tarantula or scorpion, and their stories intertwine at key points. Not only do you have the story of these creatures' survival and journeys, but there is a parallel crime saga going on with human characters.
The cool thing is that you observe the human story entirely from the creatures' perspective, and eventually, you get involved in some way as the creatures emerge from their desert homes into human civilization.
