There's probably more FAQs on this out there, or walkthroughs, but I guess I'm trying to not be totally spoiled in this.

I've made it through the canyon and temple. I have one problem, and a lot of questions

Problem: Losing my monk guide. I know he's re-recruitable as a follower but if you leave the temple (to the wasteland) if you don't come back to temple, you're in trouble (all the raiders will note you don't have a monk and attack) or if you walk out of the temple and forget to re-recruit him, same problem (raiders everywhere, gets ugly)

(It's worse if you come back from the wastelands, because then you can really screw yourself)

Is there a better way ? Or do you always have to go back to the temple and recruit him ?

More on the spoilery/question area:

Can you destroy all the raiders (and their mad monks) with out much repercussion ? (not wipe out the monks at the temples - want access to the doctor, stores and what not)

What about inside the silo/under the temple ? Can you kill all the monks there (save the guy in prison) with out having everyone go hostile when you go back up ?

The DBM - I get they are the more evil of the two, can you string them along any ? (I see how leaving your monk at the temple, my question above, can make it possible to string them along, enter their base etc with out losing your monk)

Is there a good/better/best way to solve the temple/canyon ? From the guy in the basement of the silo, I think finding/sending a real nuke back would be bad. Rose seems to act as the conscience of the player, and notes that the monks might be crazy, but they work .. I think the DBM would be worse. The raiders presence/abuse under the monk's protection is the lesser of the evils, but ..

Can I get Angela Deth back after leaving the temple ? She gets recalled to ranger center, and I've found not having someone with outdoorsman is really frustrating (waay to many annoying encounters).

(yes, I know a lot of re-play and save/restore could answer these, but man, it takes a long time ;)

When/where in temple you can leave the escort behind? I might reload earlier save if I can drop him off peacefully.

I was able to talk to militia despite killing three of their teams (nice loot btw) but I did not gain access to safe (can be forced open) nor their quatermaster/store. It was take the suicide mission or die deal instead of "friendly" recruitment speech.

As for monks, if you break titans peace, you'll have to pay double tribute at the temple gate (you'll receive 3 additional sludge containers there) and miss at least on side quest (the one from nuke grenade maker). You do get access to shops and hospital. Haven't figured out if there's any way to get prostethics from there (maybe if I reweal the militia base?).

If you lose escort early you probably wont be able to talk to raiders as they'll (most of them at least) agro monkless on sight so you loss some possible XP but you get way more killing everyone (plus the loot, man, the loot ;-p).Monks at checkpoint nor at the temple did not attack me despite killing everyone who was foolish enough to attack me.

I'm at the temple now and probably will bethray militia due to having pissed them off (I don't think they're worth it without access to their store, if I kill them I at least get all their stuff) or I'll end up killing both (monks don't like me either but at least I can trade with them. But the loot, man, the loot! lol). Or if there's peacefull way to get rid of the monk, I may reload and try another approach (at least won't piss off the militia before shopping at their place).

See, I'm proper lawman aren't I? ;-p

I had to reload a few times to figure out when I'd lost him.

As soon as you pay your tribute and enter the temple (ie just past the farting cowboys), your monk says "I'm leaving you but I'll be waiting for you ... " -- he's standing right behind the wall/gate as you enter the temple (so he's inside the temple perimeter). Hard to notice on your way back through. (and thus if you enter from the wastelands and don't go to the temple, you can't pick him up).

If you have him with you and leave the temple for the canyon, and then go back to the temple, he'll leave again and wait at the same spot. (ie so you can talk to the drunk guy who won't talk with a Monk around)

(and it seems Angela is gone - she's not back at Ranger HQ. Nuts.)

No success yet with DBM -- like you got in (and had Rose reprogram all the sentry guns..) so that I could go back hostile and shoot them up. But I'm still trying to play the scenario out.

Did find out that the nuke is a fake -- once you find the launch console or the museum brochure, the head monk shows up says go to silo 7 and retrieve the real nuke and offers peace or death (just like the DBM guys.. ). This means no more aggro monks in the silo, and you can explore it fully. Except you can't pick lock into the hospital wing/room, that aggros the doc and guards. Speaking of hospital, I couldn't get a prosthetic/cyber implant either -- says she doesn't do work on Rangers.

This is how should be happening, Angela is in a special mission already. Though before patch 3 (or maybe two) she was in the HQ but without dialogue.

Yeah, I watched the DBM slaughter the monks sent to clear their hideout, but I just watched, didn't attack.

So far, I've done the following:
- disable the nuke in silo 7
This causes the canyon to become a raider hot bed -- the DBM and raiders kill the monks and take over.
- Send nuke to monks
Nuke gets detonated, canyon becomes a waste.
- send nuke to DBM
DBM kills the monks, extracts 150 scrap every time through

So I'm not seeing any good results so far :/

I did that, too, and the result was that the DBM and monks killed each other. The raiders were not mentioned anywhere. The final result of this is that the canyon fell into anarchy which can be good or bad or neither.

Are you sure? For me it mentioned Chaos Raiders and DBM (despite me killing every single one of them in canyon, including those in their base bunker) took over and chaos reigns. I'm also pretty sure the raiders present were chaos raiders.

The raiders were gone, IIRC, by something I did earlier, and when I returend from Silo 7 and Damonata, there was a Mexican standoff between the monks and DBM going on, with me finally mopping up the rest.

According to the credits scene, the canyon then fell into anarchy.

So wether or not you eliminate DBM does change the situation a little. If you take them out, monks will be overrun by chaos raiders and if not DBM and monks will be fighting each other when you return. Ending probably will probably be the same though.
