Kill 3 or more enemies with a single N6A3, AT-S or M77 in the

Campaign or Instant Action.


Simply use one of the grenades and go into a group of enemies, make sure there's at least 3-5. The best place for this achievement is in Interval 8, just before you face the Heavy Armor with the rocket launcher. A van crashes through the door and four enemies pour out. Hit one of them with the grenade and the others will die from the splash damage.
