I'm a trophy hunter just like most community members i know around here are so i wanted to let all Community Members know if you are looking to obtain all Trophies/Platinum then the very last trophy on the list which is "Born Survivor" can cause you some trouble, but thier is a soulution..Read Carefully Below.
Trophy Glitched: Born Survivor
Solution:3 Soulutions Below
1: Replay All Chapters from Start to Finish ALL in one go/sit through. (Start to Finish includes playing the Tutorial/Base Camp Level all way to Chapter 5 in ONE sitting)
2:Try The XMB Trick if you find yourself about to die or become unable to continue with your mission
3: Worst case delete all game data & save data start fresh,you would then know the levels & should be able to get through it with careful play.
The 3rd option worked for me & i was able to get the Platinum i hope this information helps other community members..Also the game is fun for the survival type & a Trophy Hunters must have!!
