How to unlock WHAT DOES SFMT STAND FOR?
After you defeat the Blimp you will complete part of the game. And you will have the option to switch between Normal and SFMT mode difficulties in the main screen pressing . Once you select SFMT mode you should hear the alarm in the air, for this trophy you just need to survive the 10-15 seconds the alarm is ringing and if you succeed then the trophy will pop right away.
This mode is nuts and you can find your first tries hard but once you learn it, you should be able to hold the pressure and gain this trophy.
