Single Player: Kill two enemies in one strike using the environment [Bronze / 15G]
Location: Mission 1 One way to cause environmental kills is to shoot explosive barrels. During mission 1 there will be lots of opportunities to score double kills using this tactic. A great spot is in the outside area where the attack helicopter comes in as enemy backup, shortly after obtaining the predator bow. The last two Cell Operatives will be sitting behind a barricade. There are two explosive barrels right next to them. Shoot the barrels for an easy environmental double kill.
