Slay the Spire 2 1.0 release: Sep 2027Not announced: our best guess from Mega Crit's 1 to 2 year Early Access plan.
Best guessMega Crit's Early Access FAQ on Steam says it will stay in Early Access "Until the game feels great! Last time we thought it would be about a year and it took about 1.5 years. So perhaps in the same 1 - 2 year range." We count 18 months from the Mar 5, 2026 Early Access launch, as the first game took, to the first Thursday of Sep 2027 (Mega Crit ships on Thursdays) at 10 AM Pacific, the hour of the Early Access launch.

Co-op Strategy

In Slay the Spire 2 co-op, enemies scale with party size and attack everyone, so the guides advise one player leaning into support (Weak, Vulnerable, team Block), timing attacks after an ally's debuffs, taking multiplayer cards such as Knockdown, Flanking and Rally, and talking through relics and rest-site healing. Mobalytics' multiplayer tier list puts Knockdown, Flanking, Beacon of Hope, Rally, Glimpse Beyond, Energy Surge and Huddle Up in S tier.

Winning Slay the Spire 2 in co-op comes down to playing as a team rather than as two to four solo decks: enemies have more HP and hit every player, so one player's debuffs and team Block are worth more than in solo, and the multiplayer-only cards reward setting up a partner's big turn. Mobalytics' co-op guide (updated Jun 2, 2026) says a support-focused player is worth more in co-op than in solo, because Weak and Vulnerable from one player help the whole party, and PCGamesN's Nat Smith watched a Knockdown plus a partner's Defect Orbs take half the Ceremonial Beast's HP in one turn (PCGamesN, Mar 21, 2026). Co-op is online for up to four Steam friends, with no matchmaking. The game is in Early Access, and Mega Crit keeps tuning co-op scaling; each piece of advice is credited to whoever gave it. How co-op works is on Co-op Multiplayer.

How co-op changes a fight

Enemies are tougher and target everyone. PC Gamer's co-op guide (Mar 24, 2026) says enemy stats scale with party size and enemy attacks hit the whole party; Energy is not shared, everyone acts at any time during the party's turn, and all must press End Turn. Mobalytics adds that bosses get stronger defenses too: Vantom needs twice the hits to break its Slippery. PC Gamer's Evan Lahti says co-op fights the same enemies with more HP (PC Gamer, Sep 18, 2026). Mega Crit tunes this often, for example lowering multiplayer scaling for enemy Artifact, Slippery and Skittish in v0.104.0 (Apr 24, 2026, main branch Jun 19, 2026).

Everyone still needs their own Block. Mobalytics warns that even with a support player you must defend yourself, because enemy attacks reach every player.

Roles

Give the party a support player. Mobalytics says Weak and Vulnerable applied by one player help the whole party, so one support-focused player is worth more than in solo. PCGamesN's character tier list (updated Apr 28, 2026) names the Silent's Piercing Wail and Expose as cards that help the whole team, says the Necrobinder brings strong multiplayer debuffs, and calls the Defect flexible in multiplayer, able to deal damage or support.

Time your attacks after your partner's debuffs. Because players act at the same time, Mobalytics says to wait for an ally's Vulnerable before attacking. Each player's card previews show over their head, which Nat Smith says lets you coordinate, and you can resume your turn after ending it early while your partner is still deciding (PCGamesN, Mar 21, 2026).

Team compositions

The guides name a few pairings that stand out. PCGamesN calls the Regent "nearly broken" in all-Regent multiplayer parties, while Nat Smith found the Necrobinder and the Regent a "painful duo" in his own runs (PCGamesN). Smith's best turn came from Knockdown on one side and Defect Orbs on the other. Mega Crit has not named a best team, and we found no outlet that ranks co-op teams. Each character is on Characters.

Multiplayer cards worth taking

Co-op adds cards that appear only in multiplayer. On the main branch these are, per Spire Codex (game data, v0.107.1), the Ironclad's Demonic Shield and Tank, the Silent's Flanking and Sneaky, the Regent's Hammer Time and Largesse, the Necrobinder's Glimpse Beyond and Legion of Bone, the Defect's Energy Surge and Ignition, and the Colorless Beacon of Hope, Believe in You, Coordinate, Gang Up, Huddle Up, Intercept, Knockdown, Lift, Mimic, Rally and Tag Team. The full list is on Multiplayer Cards.

Mobalytics ranks them. Its card tier list (updated Aug 12, 2026) puts these in each tier:

Tier Multiplayer cards
S Knockdown, Flanking, Beacon of Hope, Rally, Glimpse Beyond, Energy Surge, Huddle Up
A Hammer Time, Gang Up, Sneaky, Tag Team, Believe in You, Mimic, Largesse
B Demonic Shield, Lift
C Legion of Bone, Ignition, Coordinate, Intercept
D Tank

What the S-tier cards do on the main branch:

Card Owner Cost Effect Upgraded
Knockdown Colorless 3 Deal 10 damage. The enemy takes double damage from other players this turn. 14 damage; triple damage
Flanking Silent 2 (1) The enemy takes double attack damage from other players this turn. Costs 1
Beacon of Hope Colorless 1 Whenever you gain Block on your turn, other players gain half that much Block. Gains Innate
Rally Colorless 2 ALL players gain 12 Block. 17 Block
Glimpse Beyond Necrobinder 1 ALL players add 3 Souls into their Draw Pile. Exhaust. 4 Souls
Energy Surge Defect 1 ALL players gain 2 Energy. Exhaust. 3 Energy
Huddle Up Colorless 1 ALL players draw 2 cards. Exhaust. Draw 3

Source: Spire Codex (game data, v0.107.1), read Oct 26, 2026. On the public beta since v0.108.0 (Jul 3, 2026), Flanking is Rare and Beacon of Hope costs 2.

Tell your team before you play a setup card. Knockdown and Flanking only pay off if partners attack after them. PCGamesN's Ken Allsop says the 15 co-op cards added on the beta in v0.108.0 often need you to tell teammates before playing them, and warns that Outrage can clutter a teammate's carefully built deck (PCGamesN, Jul 3, 2026). Those cards (such as the Ironclad's Midnight and Blaze, the Silent's Blade Symphony, the Regent's Plot and the Defect's Hibernate) are beta-only so far.

Some co-op cards were trimmed early. Mega Crit's v0.100.0 notes (Mar 20, 2026, main branch Apr 17, 2026) stopped Beacon of Hope from stacking, cut Believe in You from 3(4) to 2(3) Energy and made Huddle Up Exhaust.

Relics, potions and Gold

Talk through relics; you cannot trade them. PC Gamer says relics, potions, Gold and cards are not shared, and each player sees a different shop with different prices. Treasure chests hold one reward per player. When two players want the same chest relic, Mega Crit's patch notes call it a "relic fight"; PC Gamer says chance decides it, while Mobalytics describes Rock Paper Scissors with the loser taking a random other relic. Nat Smith says players negotiate relics toward whoever needs them most.

Some potions can help a teammate. Mobalytics says potions such as Block Potion and Energy Potion can target a teammate, and that you can inspect allies' relics, potions and decks but not their hand. Every potion is on Potions.

Ancients and events give each player their own choice. PC Gamer says Ancients and events offer each player separate options, so blessings can be split by role. More on Neow and the Ancients.

Healing and rest sites

Mend can save a partner, but it costs an upgrade. Rest sites in co-op add Mend, which restores 30% of one ally's HP (PC Gamer). Nat Smith warns that a partner who keeps healing allies instead of upgrading can leave both players too weak for the next act (PCGamesN).

Miniature Tent is stronger in co-op. Mobalytics calls it "incredible" in co-op because of Mend, and Evan Lahti says one player's Miniature Tent "hit several times harder" in co-op (PC Gamer).

Deaths are not the end of a run. PC Gamer says dead players are revived after the battle if the party wins, and TheGamer says a run ends only when all players die (TheGamer, Mar 9, 2026); guides differ on the details of revival, and Mega Crit has not spelled them out.

Communication and the map

Agree on the route out loud. Players vote on the path and a split vote is settled at random (PC Gamer), and everyone can draw on the map while choosing (TheGamer). There is no voice chat in the game; Casey Yano said in the April 2026 Neowsletter (Apr 17, 2026) that in-game voice is unlikely: "Unless something horrible happens to Discord." Route advice is on Pathing Guide.

Play the same mods. Mega Crit recommends that co-op partners run "the same exact mods" (v0.108.0, Jul 3, 2026). More on Mods and Steam Workshop.
