Unnecessary Roughness
Use a riot shield to beat down an enemy in Single Player or Special Ops. I recommend doing this achievement during the story. In the gulag it's necessary to do this.

No Rest For the Wary
Knife an enemy without him ever knowing you were there in Single Player or Special Ops. Just come close and be sneaky. Then hit him hardly.

The Harder They Fall
Kill 2 rappelling enemies in a row before they land on their feet in Single Player or Special Ops.

Two Birds with One Stone
Kill 2 enemies with a single bullet in Single Player or Special Ops. Just keep trying.


Three-some
Kill at least 3 enemies with a single shot from a grenade launcher in Single Player or Special Ops.

Knock-knock
Kill 4 enemies with 4 shots during a slow-mo breach in Single Player or Special Ops.


Desperado
Kill 5 enemies in a row using 5 different weapons or attachments in Single Player or Special Ops. Best is to try this achievement during the story. Just kill some enemies and then try killing JUST ONE enemy before switching to your secondary. Again, just kill ONE enemy, then grab a dropped weapon off the floor, kill one enemy passing by, and so on. Note, that the weapons have to be different!

Some Like it Hot
Kill 6 enemies in a row using a thermal weapon in Single Player or Special Ops.


Look Ma Two Hands
Kill 10 enemies in a row using akimbo weapons in Single Player or Special Ops. This is quite easy to do during the story-chapter Takedown. Note, that you're not allowed to switch your weapon.

Ten plus foot-mobiles
Kill at least 10 enemies with one Predator missile in Single Player or Special Ops. This is best to do at Contingency during the story-line. Just wait for some enemys to meet, then kill them fastly and loudly.

Drive By
Kill 20 enemies in a row while driving a vehicle in Single Player or Special Ops.
