Description: In melee, push 5 enemies of ledges
How to obtain:
During the storyline, you will have plenty opportunities to obtain this achievement. What you need to do is to push various opponents off ledges to their death. For this, you only need to perform the melee attack.
If you have not obtained the achievement during the storyline and completed the game already, a good location to push off enemies is at the Soviet Installation (replay the Copper Mill stage). You start in Copper Mill Yard Camp, where you need to climb a bit deeper into the mill, after you enter. A bit after you encounter your first opponents, you can swing on the rope. Then, in order to jump over to the other side, you need to jab the hatchet into the wall and jump over onto the big red tank.
While on the top, jump towards the other side and Lara will grab the ledge. After you climb up, you get behind the back of an opponent that is walking out and talking over the radio. Attack him with the hatchet and push him off the ledge (let him see you, do not perform the finisher - simply attack him in melee to push him away). Then, you can jump into the void and repeat this over and over again.
