This trophy can be won in a couple of ways..
Easiest way is to get a few people together and have a squad and then just let them do all the work and hopefully they will pull the win or you can wait until you are the last person and other person left alive and you can just sit in the storm eating food and regenerating health, make sure you have the Halo of darkness (or whatever it is called) so you take less damage while in the storm but it isn't recommended that you get the trophy this way because the storm will easily wreck your health..
