My guess off the bat is that it may have something to do with Chokeoint, since she's a key player in the Sentinels story at the attack at fort Adamant.

That’s more tied to the Void Guard, though… That’s how they find the ObliVAeon shards, after all. She doesn’t come around until they’re already Adamant.
Possibly. That's the storyline that results in their becoming Void Guard, though. The Adamant Sentinels are defined only by their teamwork practice at Fort Adamant (unless they have a new, more detailed background in the app which we can't read yet, and hasn't been added to the wiki). And of course, we don't have Fort Adamant.
It might have to do with Choke, though, in Fright Train's deck. Supposedly she was imprisoned at Fort Adamant before she absorbed a tank and walked out.
Also a good chance it has to do with their nemesis, La Capitan. My best guess is that they have to do something team-ish while fighting La Capitan.
Just tried a game where I got all four signatures in play, had all four of The Sentinels use their powers, had Sentinel Tactics in play, and had The Idealist deal the final damage. Ambuscade, Mobile Defense Platform. Sentinels were first. Then it was TLT, Grandpa Legacy, Scholar, PW AA. No unlock. I also tried to make sure all four of The Sentinels dealt damage to the villain character card, but I don't believe Dr. Medico did damage because Hippocratic Oath came into play early.
Here's another theory: while fighting Chokepoint, have all signature cards face-down in Chokepoint's area and win.
Or lose.
Is there any record of someone unlocking The Adamant Sentinels on any of the forums yet?
Not that I've seen. I can't contribute with hints or guesses since I'm a tester for Handelabra so I try watching out for unlocks in the forums.
Well, their bio mentioned lots of teamwork stuff, so I thought I'd try something. With Sentinel Tactics out, and each of their Unique cards out, I managed to play Team Communication as well as Unique Capabilities 3 times each in a turn, and then I hit La Capitan with Coordinated Assault, so.....kinda maxed out the teamwork.
Btw, do we know from MigrantP yet, do they all unlock at once, or each of them individually? I know you can mix and match which ones you use when you play, so it makes sense that they COULD unlock individually.
What I understood from the live stream was that they aren’t actually meant to play that way, but Christopher said to allow it because he knew that people would want to.
So, not I’m not in any way official, but I would think that means they unlock together.
Well, the other Variant conditions have been discovered, so everyone can now dedicate their brain power to unlocking the Adamant Sentinels.
I attempted to use all the pwoers in one round.
I was so lucky, with AA, PW FAnatic, and Gramps.
Unfortunately no unlock.
I was against Ambuscade in Zhu Long.
I had 0 signatures out.
Defeated La Capitan, with Sentinels in first spot. Played every card at least once, used every power, had all 4 of them at full health, killed her with a Fling Into Darkness.
No unlock.
Oh, and had all signatures and Tactics out at the end of the game.
Oh I really hope we can mix and match in the digital version! I doubt they implemented that (because there’s just the normal “variants” toggle).
Defeated Akash'bhuta with only the Sentinels in play. All signatures (and Sentinels Tactics) were played, although not all were in play at the same time. All Sentinels except for Writhe were incapped. All Sentinels did damage. No unlock.
(I was actually trying for part of Naturalist's unlock. But Akash came out swinging, and killed Naturalist, Sky-Scraper, KNYFE, and Mr. Fixer before I could blink, and nearly took out the Sentinels too. But I managed to get them all back on their feet, and it turns out that three blocks, a reanimating durasteel chain (courtesy of Mr. Fixer) and plenty of available ongoing destruction makes you pretty much immune to Akash'bhuta. And having four heroes kept the Brambles from locking us down. And of course mass damage is always welcome.)
Defeated La Capitan in Silver Gulch. Lost in the Past was out, Sentinels were in the first spot. All signatures, Tactics, and Human Shield were out. I knocked out Writhe and brought him back, then dealt the finishing blow to Siege Breaker with Writhe, and La Capitan with Idealist, both in the same turn.
No unlock.
I have no idea what it could be.
I believe they actually said that you can!
Defeated Plague Rat, forget where.
Had all Sig.and Tactics: Tried having Idealist die, Then Medico die, then flipping Medico using the first one-shot, and then using the Medico one-shot to res Idealist.
No Unlock
Maybe some other heros need to lose a fight with Progeny first? Weren't the Sentinels mostly training while that all happened?
Possibly even something like... if I recall the storyline as established by the ARG correctly, Progeny beats the prime wardens (using prime warden variants), Progeny beats the Dark Watch + Scholar in Rook City, and THEN something that unlocks them?
But that’s the VOID GUARD, not the Adamant Sentinels. They were Adamant long before that all happened.
Still, it's a good idea to cover the bases. As far as I know we don't have any record of it being unlocked, so there's no harm in trying.
La Capitan : Sentinels, TL Tach, Chrono Ranger : Time Cataclysm
Capitan never flipped
All sentinel ongoings in play, Writhe -> Idealist for the kill
No Unlock
Has ANYONE gotten it, apart from playtesters and MigrantP?
According to the global achievements, at least someone unlocked it (it's currently at 0.1%). Maybe that statistic includes the aforementioned people.
Steam achievements have no separation between developers, beta testers, and the general public.
So, that is probably just them, then.
Got it. Got it earlier today, and my phone crashed as I hit share. Apologies for keeping quiet until I could repeat it on steam.

Do, did you lose? It looks like you got Wrecked. With the Training Room out. Anything else you did in there?
Here is what I think you need to do.
1. All the signature cards must be out. Possibly Sentinel Tactics/Human Shield must be out, I got them out to be safe.
2. AFTER all the signatures/ongoings are out, all the Sentinels must then be incapped.
3. AFTER all the Sentinels go down, the rest of your team has to be incapped.
Ah, that’s what I did wrong. I let the rest of the team die first.
So, is Training Simulator necessary? Or no?
Don't think villain or environment matter.
Training Simulator is NOT necessary.
I have replicated your results. A good starting draw, a team of Omnitron-X and Dark Visionary to get Sentinel cards out as fast as possible, and a weak villain in the form of Gloomweaver allowed me to manipulate damage output and group HP to make the team go down in the proper order.
Used same method:
Here's my Log: http://pastebin.com/kjewavUJ
Got it, Plague Rat, in Temple of Zhu Long. I also posted my screenshot on Twitter.
I can also confirm that you CAN mix and match Sentinels. If you double click on them while selecting heroes, up at the top is a grey button that lets you look at each of them individually. From there, you can switch them each, rather than all of them.
I did all of the above, with Ambuscade in Freedom Tower. I DID have Training Simulator out.
I did NOT have Sentinel Tactics or Human Shield out.
It did NOT unlock for me.
Unlocked on Mobile at Zhu Long vs. Gloomweaver.... looks like environment and villain don't matter.
Also I can confirm that you can incap individual members of The Sentinels before their Signiture comes out.
Can confirm it works with the four Signatures and Tactics, no human shield.
Just played the same game twice on my phone. Baron Blade vs Grandpa Legacy, F6 Tachyon, Argent Adept, Sentinels at Freedom Tower.
First game got out all four Signature cards and then incapped everyone, no unlock.
Second game got out Sentinel Tactics and all four Signature cards and then incapped everyone, got the unlock.
In both games, The Sentinels were (collectively) incapped before all other heroes. Pretty sure that the villain doesn't need to be the one to incap the heroes.
My guess
Lose a game with The Sentinels in the party. Sentinel Tactics, Hippocratic Oath, Durasteel Chains, Aura of Valor, and Caligenous(sp?) Form must be in play when The Sentinels is incapped.
Things that need to be tested
- Can the loss condition be by alternate means (for example, Baron Blade pulling the moon into the earth), or must all the heroes be incapped?
- Must The Sentinels be incapped for the condition to unlock?
- Do The Sentinels need to be first hero incapped to count?
(Note: condition 2 could be required regardless of whether condition 1 is valid)
I suspect that Human Shield must not be out, or perhaps there is something else missing, because I did what everyone has suggested. Gramps Legacy, TL Tachyon, Well-Read Haka, Sentinels, and base AA vs Ambuscade in Final Wasteland.
I had every Sentinels Ongoing out, the Sentinels were incapped, the rest of the team was incapped a couple rounds later. No unlock.
I did experience a weird bug with Caliginous Form, though. It kept redirecting damage beyond the first each turn. I was only able to damage Writhe when Tachyon played multiple cards during her Play phase. Everything else got redirected, including AA giving Haka multiple power uses / card plays in the same turn.
Did you have Sentinel Tactics out?
Also, I wonder if damage immunity plays a part. If Ambuscade is immune to damage, then when damage is redirected to him, it might not register as having been redirected at all; almost as if the damage were prevented instead.
The official unlock condition for the Adamant Sentinels has been discovered by the community:
Lose a game with regular The Sentinels incapacitated at the end. The Sentinels must be incapacitated before any other heroes are incapacitated. All four Signature cards along with Sentinel Tactics must have been in play at the same time during the game.
100% Way to unlock Adamant Sentinels:
-Have all (4) Signature Cards in play for the Sentinels.
-Have Sentinel's Tactics in play.
^^^Order does not matter. Must all be in play at once.
-Then have the Sentinels become incapacitated.
-Finally the remaining heros must also become incapacitated and you must lose.
[UNLOCKED via iPhone]

Just a quick PSA. I wouldn't attempt this unlock against Ambuscade. Last night I discovered (reported it this morning) a bug with Caliginous Form. Apparently if Ambuscade is immune to damage, Caliginous Form will keep redirecting, no matter how many instances of damage he takes in a turn. While this would normally be a boon, obviously if you're trying to kill them off, it's a real pain. In typical "man Ambuscade can be annoying" fashion, Ambuscade managed to cycle back around to his Cloaking Device every turn for like 5 turns that game, so I saw the bug a lot, and I thought I was never going to manage to kill off Writhe.
I encountered the same bug. It actually wasn’t every time… I couldn’t figure out the pattern… but yeah it caused it to take awhile. I was smarter on mobile, I incapacitated Writhe before playing Calignous Form… I definitely recommend that tactic.
Got the unlock, which led me to re-discover two things:
1. The Sentinels are nemeses of each other. Bonus damage!
2. Gloomweaver's victory music. I haven't heard that for a LOOOOOOONG time. Missed you, buddy!
Just a quick question about the phrasing. I know The Sentinels have to be incapacitated first, but after that, can you lose to an alternate loss condition (Voss' minions, Self-Destruct Sequence, Lost in Time, etc) or do you have to lose to being totally incapacitated?
Hmm. I did exactly that and did not get the unlock. Weird.
if you're on Steam do you have a game log by chance?
You need to lose the game. The method does not matter.
I’m not clear on what the story reason is for this unlock condition. They get their butts kicked, so they decide to go into intensive training? If so, why do they specifically have to go down first, and then lose on top of that?
We really haven't gotten story reasons on a majority of them and that's on Christopher to explain as he doesn't give that to Handelabra. DW Setback is one example that makes no sense as DW formed before they found Mr Fixer but the unlock has everyone in DW variants except him.
So, I unlocked the Adamant Sentinels I immediately tested to see whether or not you could mix and match them. It looks like it's one or the other at the moment. Is there a button I'm missing, or are there plans to implement this? Also curious about how Sky-Scraper will operate.
You are missing a button. By default it will make them one or the other you have to browse through and select them individually when you expand them on the hero select screen.
Found the sneaky button.
It’s sneaky, but it’s definitely there. It was the first thing I made sure to look for. I gotta have my custom team. Block/Regeneration/Thump is just so good!
At least until the next update, make sure that when you lose a game with the Sentinels configured a certain way, you click New Game instead of "Try Again." It'll automatically default to base Sentinels for all 4 of them; with any luck, that'll get fixed when Handelabra manages to round up their employees after Christmas. :P
Yes, that bug will be fixed in the next update.
Because you are awesome!
Could you tell me where this button is on iOS? I am just not seeing it.
When you select heroes, double click on the Sentinels. You will get a selectio image of their text card. Just to the left of the picture, below the flip arrow is a grey button. Click it to cycle through the Sentinels. If you want to switch versions ofr that one, click the Variants button in the bottom right.
Not completely sure about on IoS since I do not have the game for an appropriate device. However for the devices I do have. It is a little shadowy image found right under the arrow used to show the incapacitated side when looking at the expanded card view from the hero select screen.
It appears to show be there to show other cards attached to the hero. I first noticed it on SkyScraper's Card to show her different sizes. If you can find that button for the Sentinels you should be able to look at the individual heros and press variant to change the particular hero you have zoomed on to its varient. Repeat for each hero you wish to change.
THANK you! I was not seeing that button for my life.
