[quote name='SneakyPenguin']Technically in Twin Snakes I think you can tranq them.
But even ignoring the previous entries in Deus Ex the boss fights are lame because the game is geared towards letting you make any character and beig able to play that way. My character was a stealthy hacker with barely any armor, health, or combat abilities and it worked fine for most of the game. Getting thrown into a firefight with a tank like Barrett was murder. I stopped playing for months after I encountered him.[/QUOTE]
Yeah, no, I get it -- was Barrett the leader, boss fight 3 or 4, the second china boss?
Because I did that on hard, as a stealth based player, with the chip. And it

ing sucked. I thought I was done for. I almost quit, I was raging so badly. That fight just sucks if you get the odds stacked against you.
And even in Twin Snakes, if you try to tranq the bosses, I think you need to deplete a "health" meter for it, which is no kill, but still, you're in a firefight with a boss in some capacity.
