The 2 guards can be bypassed with the good timing. The achievement was bugged (the daemon in level 7 always trigger a detection), but someone made a patch to correct it. Make sure you applied this patch. It also add an in-game tracker to help you be sure you were not spotted by someone.

No KOs on level 7 and 8?! That's darn impressive. I am not sure if these 2 annoying guards on level 7 can be bypassed that way, let alone if you play the whole game in one sitting. Completed all the levels on Cyber Terrorist, but didn't get it, eventhough i was playing level by level until i will ghost stealth it (didn't work out without KOs on 7 and 8 ofc). Completed it on Easy with no KOs - still nothing.

Yes I did the Sneaky Bastard achievement in Cyber-Terrorist difficulty, this way you know if you're detected right away. But you should be able to get it on any difficulty. I didn't knock out anyone during my run.

Hope you'll get it ! Good luck !

Hi there. I have noticed you on the forum regarding ROOT 2015 achievements. Tell me, did you get the Sneaky Bastard one on cyber tettorist difficulty? Did you knock out anyone during the whole run?
