arugulaKhan: I had no idea you could switch weapons for the challenge. Learn something new every day :)
I didn't think it was possible either, but after some "trial and error" (see, this is where
I try several times - to break my games ^^), I found there is a brief window between stepping up to the firing line and the timer begins.
If you try to swap from your inventory after you got the default weapon in your hand, you just get a message saying "You cannot do that".
arugulaKhan: Alternately, if you have Sandevistan, turn that on :) You'll get about twice the time.
Ugh, I keep reading about that feature, and every time it becomes viable, I forget about it... For sure, I got 20 Reflexes, and have bought a Sandevistan cyberdeck, but when I ran around testing it, I found I can no longer scan or even interact with access points.
Enemies, surveillance cams...everything became unavailable without a Netrunner cyberdeck.
And as I also got 20 Intelligence on my current character, Sandevistan suddenly became way too niche to be the primary ability. Whereas a Netrunner cyberdeck and Quickhacks are useful almost all the time.
Legendary Cyberpsychosis Quickhack and Spread number / Spread distance perks...you can take out whole groups of enemies, without even being spotted with that.
