Campaign Mission: Requem / Soft-Lock 
  
You can get Master Chief Soft-Lock in Side a broken ship right in the beginning of the mission above. 
  
1.Have the player run to the right as you start the mission. 
2.Go in side the ship were you find a video file about a A.I. 
3.When the player is inside the ship move to theright side outside of the ship and jump on to the side of the ship. 
4,When player jumps on the side of the ship and falls the player will fall in a hole thats on fire. 
  
Note: I found this just explore your game looking see if there any hidden items or records, 
The problem is other then you are stuck that when you try to Revert to Last Save the player 
will revert into the soft-lock again. I had to start the mission over again. Its lucky that it happens 
in the beginning. If i was later in the game and im on legendary and i was half way on the mission 
and i had to restart the mission I would have been mad. I hope i dont hardlock. Soft-lock repeats if player stay to long and Corotana tells 
you were the Waypoint is. 
  
  
Just adding this reply to help out and not have others get stuck like i did, it kinda sucks to get traped.
