Yeah I fell for it big time, but my first play through I was determined to do everything, even side quests, and playing a stealth character I didnt want my augments randomly shorting out on me, cloak especialy, while sneaking around, I didnt think about the consiquences till that cutscene where I said to myself "oh sh*t"
I tell ya I must be a glutton for punishment, because my first playthrough, going for stealth and pacificsm on "give me deus ex" difficulty, I was pulling my hair out at the boss fights.
Ended up beating that one by standing close to one of the walls he jumps over on the east or west side of the room, wait for him to start to hop over (since his cloak temporarily disables as he does and he is vulnerable and cant shoot back till that animation completes) looking through the small slits in the walls to know when he is approaching, shoot a few bullets into him as he is jumping over (the shotgun I found in that room was particularily useful since all I had on me at the time was a combat rifle, stungun and tranq rifle) run to the other end of the room (opening drawers on the way if I could spare the time for ammo and painkillers), save game, repeat... for a good half an hour! was so relieved when he finally died.
And was super proud of myself when I got my pacifist and legendary achievements yesterday afternoon
