Paint 10 enemies with a single threat grenade.

Mission 1: Induction

After you take out the swarm, you will go through a lobby area that has a ton of enemies. Around 4 will zipline down first; you want to kill them. Now, simply throw a threat grenade ( [ Register or Signin to view external links. ] on PS4 and [ Register or Signin to view external links. ] on PS3) at the back of the room. If done right, you will highlight way more than 10 and the trophy will unlock shortly afterwards. There are many opportunities to get this trophy in the game, and you will more than likely get it on accident. But this spot is the first possible place to earn the trophy.
