Achievement text: "Gain 10 kills with the AimBot augmentation"
This can only be unlocked via cheats, and is the only achievement that can be unlocked while cheating. It involves installing an augmentation that isn't present in the campaign or survival.
To get this quickly, start a new survival game on Cathedral. Wave selected doesn't really matter.
Grab a sniper rifle and the recirculator augmentation. Install it and upgrade it to level 4. Upgrade your rifle skill to Master.
Open the console with the tilde key (`), and type the following:
set human bCheatsEnabled true
augadd augAimbot
A new mod will be installed in your eyes slot. Upgrade it to level 4.
Hit the button to start the wave, then head outside and face the bridge. Equip the sniper rifle, and press F8 to turn on the aug when you see an enemy. You will start performing headshots on enemies. Turn off the mod when no enemies are in view, as this augmentation is a battery eater. Once you've killed ten enemies with it, you'll get the achievement.
If you do this in campaign, DO NOT SAVE. Your save will be marked as having cheated, so you will not be able to earn any further achievements on that save.
