Sharpshooter is an achievement that requires you to complete a mission with better than 90% accuracy. This achievement is repeatable.
- Using a weapon with auto-aim, such as the Autogun or Prototype Rifle, can greatly boost your accuracy.
- Flares also provide a limited auto-aim.
- Certain weapons allow you to achieve over 100% accuracy per shot; so a few carefully placed shots will boost your accuracy sufficiently.
- Alternatively, shoot a few times, but make sure you hit and allow your team to carry you through the rest of the mission. Not recommended on pub games.
- Shooting at doors count as hits, which allows you to artificially increase your accuracy.
