In order to unlock New Game+ and it's many variations, you have to be the game at least once. This can be done on any difficulty. If you want a little bit of variety in your second playthrough you can choose from the following NG+ Variants:
Classic
Playing Classic NG+ changes the look and feel of the game slightly to call back to the original Dead Space game. Difficulty increased and in-world aiming is turned on. Necromorphs do increased damage.
This mode unlocks the Devil Horns.
Pure Survival
Pure Survival turns your NG+ into an episode of one of those survival shows on the Discovery channel. You will find no health, ammo, or stasis packs in the world, only raw resources. If you want a health pack, you better dig for the material to craft one.
This mode unlocks the MK-II Overclocked Parts Set and Mega Resources Deposit.
Hardcore Mode
This is the hardest difficulty mode in Dead Space 3. It's Impossible Difficulty and you cannot die. Not once. Because of Dead Space 3's auto-save, they've done anyway with any save limitations and just said flat out that you'll be sent back to the beginning if you die.
This mode unlocks Retro Mode
Star Citizen is an upcoming space trading and combat simulator video game for Microsoft Windows. Star Citizen will consist of two main components: first person space combat and trading in a massively multiplayer persistent universe and customizable private servers (known as Star Citizen), and a branching single-player game (known as Squadron 42). The game will also feature VR support.
