How to get access to Ouroboros?

I've been trying to get access to Ouroboros for a while now. As I understand it:

1) You basically need to do a time travel mission, which should give you a badge and unlock a power.

2) Or ask someone with access.

Now I don't like the second option. I would like to unlock this access through some kind of mission/story, not just asking someone in global chat. I'll do that if that ends up to be the only way to do it.

I can't find any way to do this though some kind of mission/story. There are two main things I've tried so far:
A) I've done the storyline for the Midnighters that gets you to Crimeroa.
B) I've placed a crystal in our base that gives access to old missions and did one of those story arcs. I did all missions, in the end it says "Completed Ouroboros task force" or something similar.

I'm level 43 now and have no clue what other "time travel" I could attempt to unlock this.

Any suggestions are welcome.

See the Entrusted with a Secret badge page. It lists all the ways you can get the badge which gives you the portal.

At your level, you might want to try grabbing one of the Recluse Victory exploration badges. The PvP areas aren't too densely populated (or, at least, they weren't on Protector when I got the Ouro power for my first character that way).

It's possible to see a "complete" message for Ouroboros, but not actually be done. I've done that a couple of times. If you're still "on a TF" you're not done. Talk to the final contact. Ouroboros should end automatically and disband your TF. If it doesn't you still have a phone call to make.

Also, if you're blueside, you can use a base teleporter to get to the Echo of Galaxy City. Then use the train to exit the zone, which will have an option to go to Ouro.

yeah check out the badge, it lists the missions. Blueside has a plethora of choices, from Mercedes Sheldon to Faultline to.. like others, I forget all of them, because I typically snag one by either of those 2.

Redside you've got a lot fewer options.

The one arc that always works is the Dark Mirror one starting at level 20 on both sides

You get access to Ouroboros when you finish the last of the two contacts, Field Agent Keith Nance and his superior Something Agent Jenni Adair for heroes and Dean MacArthur and Leonard for villains, because of what you find at the end.


Edit:
The simplest way, though, is to ask someone else to drop an ouroboros portal and use it to go to Ouroboros, collect the explore badge at the top of the building's point and voila!


I'm guessing the alternate dimension story arcs may possibly award access as well, such as the Destined One arcs in Grandville or the Praetorian arcs in Peregrine Island.
(Edit: Seems the wiki page confirms it.)

If there's no one around to open an Ouro portal, the quickest way (IMO) is to go to Recluse's Victory, go to the train station, and run straight out from the front of the station. You'll end up in a narrow alley. Run for a couple more seconds and you'll get one of the aformentioned exploration badges.

If you do the Doc Delilah arc in Faultline you get the badge for that.

I always hated having to ask someone else to open a portal for me. It feels like begging.

The Midnight Club is actually operating in secret though. Mender Silos expresses surprise, even exasperation, in one of the incarnate arcs when he learns that people are traveling through time via means not known to him or his Menders. So I guess it kinda makes sense that Cimerora would be the one time travel mission you don't get an Ouroboros portal for.

Nobody should feel like they are begging for help when asking for someone to drop an Ouro portal. Some people go out of their way to drop one for you. Heck I've seen many times where someone in Atlas Park ask for a portal to be dropped under the Atlas statue, next thing you know you got 10 people dropping portals under the statue just for the lulz lol. And if I happen to be in an area where someone needs a portal dropped I'll drop it for them. On villain side though if there isn't anybody in front of the Arbiter you may have to wait a few minutes for someone to come after asking in Help chat. You can almost always find someone willing to help. That's what I like about this game.

Edit: Don't forget, in order to use someone else's portal you need to be at least level 14.
