Snake in the Grass Achievement
Snake in the Grass15
While in Tall Grass, kill 50 soldiers.Tall grass is everywhere in this game. When you walk through it while crouched, there will be a white outline around Karl. Karl may even make a comment about using it to your advantage. Any kills made while in this cover will earn progress towards this achievement; just make sure you remain crouched or prone.
As with many other cumulative achievements in the game, you can find a good spot with a clear sight to a few enemies then save your game. After the enemies are dead, just reload that save and keep repeating until the achievement has unlocked.
To check your progress, press then navigate to Service Record > Medals > General and look under the ‘Combat’ heading to see your medal progress.
