This Integrated Strategies theme's updates have been concluded on the Global server of Arknights. As such, the contents of this page and the related subpages have been archived.
Crimson Solitaire introduces new mechanics that becomes the future standard of I.S., most notably the fact that I.S. themes are now permanently available.
Introduction
Beneath the darkening sky, you find yourself lost in a fog-shrouded forest. You are in desperate need of safe shelter to pass the night, and it appears that the ominous castle ahead is your only choice.
Now can choose between three Rec. Voucher choices of specific classes when starting a run, instead of starting with an Elite Rec. Voucher and two Rec. Vouchers of random classes (see Integrated Strategies#Starting Operators for more information). The old choice is now available as "As Your Heart Desires", unlocked after completing a run.
Temporary Life Points during operations are now displayed as a shield icon to the right of the LP counter outside of operations.
Operations can be distinguished by the ISW-NO code.
Certain Encounters can force the player into a unique operation distinguished by the ISW-SP or ISW-DU codes.
Emergency Operation
Some violence may well exceed your expectations, a very common occurrence.
An ISW-NO operation with various handicaps, similar to those of Challenge Modes, which always awards a Collectible when cleared.
Dreadful Foe
Criminals, ruffians, and the damned... You're in trouble.
An operation featuring I.S.-exclusive bosses, which can be distinguished by the ISW-DF code.
The 3F Dreadful Foe awards a Super Rare Collectible (chosen from two options) when cleared, regardless of whether the boss is defeated or not.
The 5F Dreadful Foe will end the run when cleared unless the player has met the requirements to enter 6F, in which case it behaves like the 3F Dreadful Foe. The 6F Dreadful Foe will always end the run.
Encounter
New friends, old rivals... Strange encounters never age. Only scars stand the test of time.
A random event.
Boons
A little bit of help for your journey.
Gives a random Collectible, which is unknown until actually given. Some Boons allow the player to choose from two Collectibles, one Rare and another of a random rarity.
Safe House
Quiet, comfortable, and secluded from the castle's trifling matters. It's time to take a break.
Gives a free reward of the player's choosing from three of the options listed below:
17:03 There is fog covering the entire area, and our squad has lost our way. Are we pushing forward, or are we merely dissolving ourselves away?
Reverberation
The mist has completely overwhelmed you. There is no longer a need to seek a way out, for this has become your home.
Ⅱ
Sunset Courtyard
19:24 The courtyard is filled with the sunset's afterglow, yet that is not the color of hope. Come in, come in, esteemed guests who have wandered astray. The castle welcomes you.
Reverberation
The castle has numerous trials in store for its visitors, and you are unable to pay the price of failure.
Ⅲ
Homeland Remnants
20:36 As the mist spreads into the castle and the vines make their way up the columns, the dark night appears to have retreated elsewhere for the moment. Do remember as you enjoy this moment of respite, however, that darkness is always right around the corner.
Reverberation
As you succumb to the dark shadows, you too will become part of the history of this place.
Ⅳ
Nightmare's Prelude
21:53 Darkness falls, the candles throughout the deserted castle begin to light up by themselves, and the silent Nightzmora begins to roam the shadows in search for prey who have lost their way.
Reverberation
The candle flames flicker ceaselessly, just as you yet remain in this old castle. You surrender to your endless nightmares, never to awaken again.
Ⅴ
Blood-soaked Corridor
00:00 Blood moons often signify the beginning of unfortunate tragedies in written accounts, and this omen is now shining down upon us through the windowpanes that line the corridor.
Reverberation
What will emerge beneath the blood moon? Panic? Fear? Frantic wailing? So be it. You have experienced it all.
Ⅵ
Hall of Desires
--:-- The purest and truest desires, standing above all time, have engulfed this space whole. Here, there is nothing but the endless thirst for aesthetics, fine arts, and perfection.
Reverberation
Too bad. You are not entirely unblemished.
Additional information
1F consists of 4 nodes with Rogue Trader as the last.
2F consists of 4 nodes with Boons as the last.
3F consists of 6 nodes with a Dreadful Foe as the last.
6F can only be entered by clearing 5F while having the specified Collectible listed below and consists of 4 nodes, always in the following order: Rogue Trader > Safe House > Emergency Operation > Dreadful Foe (varies depending on the Collectible required to enter)
The 5F Dreadful Foe only awards the EXP and Ingot when cleared if the player fulfills the condition to enter 6F, as doing so otherwise will end the run instead.
The curtain falls, and the actors all step off the stage. You have found those who you were looking for, and your exploration of the castle has come to an end. Perhaps it is time to return to a normal life.
The curtain falls, and the actors all step off the stage. You have found those who you were looking for, but no one can say for sure that your exploration of the castle has come to an end. Perhaps this is only the beginning...
Condition
Complete a Formal Investigation run with the Crimson Finale ending and do the following steps in a single run:
Optional: Before reaching All I Ask of You, obtain the Blank Suicide Note from Encounter: Reprieve Encounter, which requires the player to obtain the Useless Scissors from Encounter: Crazy Puppets at the cost of 3 . This will disable the Big Sad Lock's HP regeneration, making the Dreadful Foe much less difficult.
The host raises the curtain! He bows to the audience alongside his actors as all kinds of tragedies and comedies begin to unfold. He is the one who sets the stage, and he is the one who brings the show to an end. Be sure to offer him flowers when the show is over.
Condition
Complete a Formal Investigation or Calamity Faceoff run with the Ridiculous Comedy ending and do the following steps in a single run:
Obtain the Stand-in Actor by clearing the 3F Dreadful Foe.
Obtain the Abrupt Realization from Encounter: A Gathering of Followers in 5F. This will cause the player to enter 6F instead of ending the run upon clearing 5F with Twisted Every Way as the Dreadful Foe.
Every word written by the Playwright is true. The truth is blood, is tears, is life, is death, but the truth of the Crimson Troupe goes even deeper. Seek it, discover it, and escape it...
Condition
Complete a Formal Investigation or Calamity Faceoff run after Crimson Solitaire's Expansion II on December 27, 2022 and do the following steps in a single run:
Obtain the Dance of the Condemned by clearing Bound by Self, accessible by choosing "Get closer and eavesdrop" in Encounter: Don't disturb them which will only appear on 1F to 3F.
Obtain Act 1 by clearing Observation, accessible by choosing "See what they're writing" in Encounter: Revenge Story. This will cause the player to enter 6F instead of ending the run upon clearing 5F with New Chapter as the Dreadful Foe.
An example of Phantom & Crimson Solitaire run's result screen (only showing the Operators due to lack of space)
When a Crimson Solitaire run ends, the credits (which can be skipped and viewed again from the result screen) will roll (after the ending if the run is completed), showing the player's nickname under the title "Blood Diamond" and their Operators as the "casts", and logs the player's actions throughout the run.
