Mainly just adding my own questions to yours...
I generally take the AMR sniper rifle, 'cause it usually incapacitates guys with one shot. Not really sure what the second primary weapon I should use is though. I have the AMR assault rifle, just for that little bit of extra "am I using the gun I want to use" confusion, or the shotgun that your guys can use, both silenced. Never used a GL in the game yet
I think I gave the AMR a go, but even with lethal rounds it wasn't penetrating those damn riot visors. Took a few shots to *knock the helmets off* even, what the hell.
The battle armour though: is it possible to tranq guys wearing it? I usually go for the outright murder route, despite the Heroism penalty, because I didn't think tranqs were useful for that...
Pretty sure those assholes are completely immune to tranquing unless you (or Quiet, I guess) knock their helmet off first. I've resorted to just meleeing them, but I think someone said less-lethal shotguns can take them down eventually.
What about secondary weapons? Always the tranq gun, or something lethal? (I've actually never looked at the secondary weapons selection )
As someone pointed out, the riot smg is actually amazing. Much more ammo than the tranq pistol, and a headshot still incapacitates with one shot. Eventually you can put a proper sight on it which fixes the accuracy issue.
Do you guys Fulton the enemies, even if they're crap? Use them as bait when they scream and shout, or try to get them silently?
Yeah I tend to fulton everyone. Sometimes I take the time to wake them up and threaten them, since that doesn't wear off with time (only with alerts, or being found).
Do you also have the nukes? They're ultra expensive (in terms of resources, anyway) but are they actually good, or do they just encourage people to try to take them away?
Pretty curious about this too. The game keeps talking about them as deterrents, but then at some point I'm pretty sure the game told me that enemy nukes were no longer a deterrent against me. Since I've done very little FOB, that makes me think nukes aren't much of a deterrent at all.
