Dead Space 3 will be the first game in the sci-fi action adventure series to introduce co-op, which can be played on a couch with a buddy or online with a complete stranger. Although this does not effect the narrative or gameplay, the player controlling John Carver will experience dementia and see/hear things Issac will not. Watching this video shows how the dynamic between the two players will create some memorable and tense situations. Check out the co-op trailer below.
If you pre order the game you get the Limited Edition free which contains the Witness and First Contact Suits as well as the Evangelizer a combination of an assault rifle and shotgun, plus the Negotiator Weapons a limb cutting tool powered telsa.
