I am almost done with the quest "Still in the dark".After that i wanted to do the quest "For auld lang syne" but i know you have to do some prerequisites to be able to have him talk to you about the quest.I have a strategy guide and it lists like 7 things to do to get him to talk about that quest.I was just wondering if anyone knows how many of those i need to do because if i don't need to do all of them i was just gonna go for the easyer ones so if anyone knows the answer to this question thats would be great thank you

Sounds like you know more than me! I'm enjoying him as a companion, refreshing change from Boone

You have to at least start one of the main faction quests and reach the point where the faction asks you to deal with the Brotherhood or Omertas. If you help the Legion, you can get the quest by upgrading the securitons at the fort, killing Mr. House, and then uploading yes man while Arcade waits in the lobby and is your companion. When you go down, he'll give you the quest.

Actually, the OP is asking how many things you need to do with Arcade BEFORE the quest starts (like visiting Repconn with him, or the Crashed Vertibird, or the Nuclear Test Site...).

I have the same question. Would love it if anybody knows. I can say, at least, that I skipped 2 or 3 things on the wiki (or did them with companions other than Arcade) and was still given the quest.

Don't know how much but I know that if you go to the Fort with Arcade and choose the option "I want to see what caesar is doing and get the hell out" you will get the minimum loyalty needed for the quest.

It all depends on what path/faction you're supporting. Some paths you don't technically need to get any approval history with him and doing so just means you can start it earlier. Other paths mean you must gain approval points. So....hard to answer definitively.

Bingo.
The Remnants are awesome in the final battle!
Auld Lang Syne is a must-do mission, it's all worth it when their Vertibird appears over the dam. :rock:
They are in full Enclave power armor with miniguns, plus old Doc Henry in a spacesuit with plasma.
They will fight at your side, across the dam all the way to The Legate.
However, if you choose to fight The Legate (foolish in my opinion) the Remnants will probably die...
But so will you! So it's all good.

I just went through all of his scripts and dialogue options in GECK and updated both his page and the For Auld Lang Syne page on the wiki (link below). So those are correct.

The short answer is that he will offer the quest late in the game, either just before the assault on the dam or after House or the Brotherhood has been dealth with (depending on which faction you support). The simplest and most convenient way to get him to offer it as early as possible is to go to the crashed Vertibird and wait for him to comment, then travel to REPCONN HQ and wait for him to comment. Though unless you're already in the endgame, he won't offer the quest immediately. Read the page for the full details.

When doing the quest, it's really pretty straightforward, but one important tip is to make sure to wait and complete the dialogue with Arcade after each one of the recruiting conversations with the 5 Remnants. If you've been fast-travelling and running fast, he could be behind you and need to catch up. If you start another recruiting conversation before you've had the conversation with Arcade about the previous one, you run the risk of glitching the quest badly.

Keep multiple save games. But you knew that already, right?

You generally only need two of those "trigger" moments to get him to trust you, i would suggest going to the Silver Rush and REPCONN HQ.

Edit: The Vertibird can be a bit harsh at lower levels.

I guess if a player's finding walking to the Vertibird harsh, they're not ready to take on Gannon's quest or the endgame anyway.

Also, the Silver Rush isn't a trigger for the quest. He speaks there, but it's just flavor. There are a lot of places in the game where he'll make a comment, but only the Vertibird and REPCONN HQ are immediate quest trigger points. The other ones involve dialogue, and in some cases quests.

The easiest one is definitely talking to Dr. Hildern, then saying "I'm glad there are people like you around" when Gannon makes a comment about him. That's 2 points right there.
