Relic Finder
Find the strange relic.
The strange relic is located in chapter 15. You will need to rub the touchscreen to get rid of the dirt that is covering the relic. Use the touch panel at the back of the ps vita to move the relic. Once it has been cleaned 100% you click the mark in the bottom right corner and the trophy will pop.

Steel Fist Expert
Defeat ten enemies in a row with a single punch, after softening them up with gunfire.
A good location to do this is in the very beginning of Chapter 9, right against the first 10 enemies. Make sure you set your difficulty down to “Very Easy”. You can replay this chapter at any time via chapter select from the main menu. Hit normal soldiers with one pistol shot and the shotgun enemies with 2 shots. Once an enemy has been hit you run in front of them and press the square button (or use the touchscreen). Kills from behind won’t count towards this trophy (neck breaking).
Stay on distance when the shotgun enemies are coming in. They can become a little dangerous otherwise.
