Sterling Effort

Sterling Effort is an achievement in Metro 2033.
==Overview== 
This achievement is awarded for killing a total of 50 mutants with the trench knife. This can be a rather tricky achievement to earn as the knife requires a few hits to kill a mutant and whilst attempting to kill one with it can leave the player rather defenseless. Kills with the alternate attack of the throwing knives do not count towards this achievement.
On the level Cursed waves of mutants will rush a central point non stop as long as you do not complete any of the mission's objectives, which allows you to kill 50 mutants quite easily.
