A great guide on the official forums.
Evolve is a 1-5 player asymmetrical, co-op, competitive FPS-the Hunters, TPS-the Goliath video game using CryEngine3 and being developed by the creators of L4D. My impressions from research is that Turtle Rock will be making extensive use of light and dark, slow and fast, quiet and frantic (not to mention the tracking of footprints!!) to create an emotionally intense and unique experience every time you play the game (see 1:58 – in Why Evolve I Not Just Another First-Person Shooter). Does it show that I am ready to rock an Evolve wet-nipple T-Shirt and pre-order this puppy?
