Dead Space remake secret ending: how to unlock

Dead Space's remake has a secret ending that didn't exist in the original game, and you're probably wondering how to unlock it.  As our Dead Space remake review says, the EA Motive game is full of fresh additions to one of the best survival horror games ever made. All you have to do is get to the end, where a bunch of new features open up.  Once you've completed Dead Space for the first time, you will unlock New Game+ mode, which allows you to take all your unlocked weapons and upgrades back to the start of the game, where you will have to deal with new enemy variants.  As well as having to fight tougher foes, there are also 12 Master Fragments to collect if you want to trigger the secret ending.  Below we will list all the Marker Fragment locations, as well as the chapters in which they are available. Don't worry if you miss any, however, as you can always backtrack using the tram system. Just don't start Chapter 12 until you have them all.  Marker Fragment #1: Find this in Tram Control in Chapter 1, locate
