Meh i think i screwed up somewhere, 2nd boss thing, i just cannot get a beat on her, most of the praxis ive put put into hacking and other stuff, so i dont have typhoon or any dermal armour went into the fight without really knowing it was there and ive not got any nades.. do believe im screwed.
I had no armour or combat upgrades at the time too, it was tough but my tactic was to keep moving constantly, take a couple shots when I can and move on. Keep hit and running, you will regen if you get hit a bit but the boss wont, so just be patient and don't try to rush it.
For the person who asked about AUGs, I would suggest jump height and lift heavy objects can be useful as it will give you access to areas normaly unavailable, as will the breaking walls but usualy I found the wall breaking just opened up an alternative way to get around a hack, so in most cases wall breaking is less of a priority, same with the safe fall aug.
If you plan on using stealth more than combat then I suggest augs that help with tracking, hacking and cloak. If you don't mind killing then armour and steady aim upgrades can be useful. Also try and get the takedown 2 oponents at once, It was SO useful when I got it, I just wish I got it MUCH earlier in the game as I wasted so much time trying to disable 2 enemies close together when I can only takedown 1.
