The downloadable content includes New Game Plus and Challenge rooms.
New Game Plus will let you start a new game with any weapons, abilities, and inventory items from a previous play through. Now you can do what you dreamed to do to bosses that you couldn’t do before because you didn’t have the right weapon.
Challenge Rooms are two episodes of “save the little sister”. It’s not as simple as it sounds, however. You’ll have to solve a tough puzzle in order to save her as well as undergo tough procedures such as fight a Big Daddy weaponless or survive a room of Splicers.
See if you can handle it all tomorrow as this add-on pack hits the PlayStation Store for $9.99.
