Where is the start to Explosions 101 Coop?

[Steadfast]

Hi, i've searched a few minutes now and haven't found anything yet. How do I get into the Coop Mission Explosions 101? I can't find it in my Matchmaker and I can't find an open quest for it on the map. I am currently at the Iron Demon Ranch, have an ego ratng of 149 and have no active quest (Enter the Law Keeper and The Searchers is available).
I have a Coop Map available named "Liberate the lost" But I don't know where from nor where I get that explosion 101 thingy from.
Any help would be appreciated.
Cheers
Daniel

You unlock more coop maps as you progress through the main story. Progress farther and you'll unlock it later.

Some coop maps are unlocked by completing story missions, and I believe others are unlocked by achieving a higher ego rating. I believe Explosions 101 is tied to story missions. You should be pretty close to unlocking it, keep doing story missions and you should see it become available shortly.

Ah, I thought it is the starting coop map. Is "Liberate the lost ones" the first than?

Indeed it is.

Pretty sure it unlocked for me after doing the mining mission (freeing the mine complex for that nice Lawgiver Cooper). It seems a big buggy though (Exp 101) as I've been in there a couple of times and just had an empty complex to run through...

Mine unlocked just as I was entering San Quentin Ruins to begin the 'Raid on San Quentin' mission.

As far as I know, they are no co-op missions that require you to complete certain mission, I'm not sure about the very first one. We are very close at the start of the story with my girlfriend (before Fine Tuning mission on Mount Tam, no side missions done at all) and we have all 7 missions unlocked by now.

Someone please verify me, but I think the requirements are as follows:

• 200 EGO — Liberate the Lost
• 300 EGO — Explosions 101
• 400 EGO — Soleptor Excavation & The Motherlode
• 450 EGO — Island of Lost Soldiers
• 500 EGO — Commandeer Cronkhite & Scrapworks Salvage

EDIT: Forgot to mention - the reason yo use people running in mission with lower levels of EGO is because only the party leader must meet the requirements, the other party members just need to finish the tutorial to be able to join the party.

Thank you for the info! Do you or anyone else know whether entering random co-op might take you to one of the maps you haven't yet unlocked? for example i haven't unlocked island of lost soldiers yet, could random co-ops take me there after a few tries? (with the appropriate random group leader ofc)
