This is a mission challenge where you need to kill 5 enemies from very close range using the sniper rifle.
"Kill 5 enemies with the Sniper Rifle at less than 5 metres range."
- Try going for Headshots since hip-firing the sniper rifle would be ineffective without high accuracy clothing and the two accuracy skills purchased.
- Another method to getting this achievement is to no scope the enemies at point blank. This method takes a lot of luck to do though. Be warned, two shots may be needed to drop an enemy.
- Use Stun Grenade against the bots.
