It's been years since I finished the base game so I had forgotten something about basic mechanics, but apparently you can use the multi tool to hack computers as well. This helped me get the "Too Hot to Handle", as it allowed me to use the computers to disable the cameras and turrets; didn't have enough points for disabling the drones, but they were easy enough to avoid.

Thanks for the guide !

Concerning what Futeko said, I'm not sure if that's the case. I emptied most rooms accesible before meeting him and didn't tried to hit him in the bar (even if I felt similarly !) I didn't really paid attention about what he said but didn't skipped any dialogue and do not recall any mention of this harassment case. What I remember from these notes and documents is that Blade's HR head seems to be an insufferable person that likes very specific rules. Nevertheless, if this would be a consequence of your action, it would actually be a cool feature, especially in the context of a first playthrough.

Good guide, thank you!

Funnily I managed to get through in one of my first few attempts this morning. Guess I had to sleep on it!

The cameras have a cone of vision and limited range. Use your radar map to see where they are pointing and be patient so that you can move while out of their vision range. This video is also made on Give Me Deus Ex so it should work the same for you. Good luck

How the hell did you run through the heat room at the top of the funicular (46:50) right over the top of those heat detectors and not even come close to attracting the cameras?

Maybe it's because I'm playing on "Give Me Deus Ex" but I can't so much as enter the room without the cameras becoming suspicious. Even when they're facing away they immediately look back if you come even close to a heat detector. I can only get about half way through by the room by going up the middle, but from then on it's basically impossible.

About "Knock Knock" - during my run of System Rift, I did a non-lethal takedown on Slaw in the basement of the bar (I got sick of being treated like dirt with no consequences). And I don't know whether it's because of that or because of the difficulty (Give Me Deus Ex), but he did not open the door for me right away - he first asked me for a favour. Namely, he asked me to retrieve a file from Human Resources about him (a warning for harassment, located on a pocket secretary).

Only after returning with the file did he open the door for me - and he even referenced the fact I had already knocked him out once in the bar when he asked me to knock him out (again) afterwards.

Chamber 209, you don't even have to risk your life or use the Rebreather aug. There's a valve to your left in a cabinet just before you enter the Server Chamber.
