Devolver's First AAA Game Is All Army Attack: A Roguelike Auto-Battler Coming to Steam in 2027

All Army Attack is Devolver Digital's first AAA game — and the joke is the title itself. After teasing fans on November 9, 2026, with the promise of its first AAA title, the indie publisher revealed on November 10 that AAA stands for All Army Attack, a chaotic large-scale roguelike auto-battler from developer BlackLight Games. The game, which unites animals and plants against a formidable cosmic threat, launches on PC via Steam in 2027, and a playable demo arrives November 16 to 23 as part of Steam Auto-Battler Fest. The Steam page is already live.

All Army Attack: The AAA Joke Devolver Could Not Resist

Devolver Digital has built its whole brand on this kind of mischief. On November 9, the publisher posted on X that it would announce its first AAA game the next day, and the games press spent a day guessing what a big-budget Devolver title could possibly look like. The answer, delivered on November 10, was a game literally called All Army Attack — three words, all starting with A. It is the same instinct behind Devolver's long-running Grand Theft Auto VI dare: the publisher promised to release a game on the exact same day as GTA 6, and followed its launch to November 19, 2026, with Volvy's Adventure: Reslimed. Nobody who follows Devolver expected a straight announcement, and the reveal landed exactly as intended — as a punchline with a real game behind it.

The reveal trended across gaming social media within hours. That is no accident: Devolver timed the announcement for the week GTA 6 pre-loading began, when the whole industry is watching November 19. The publisher behind Cult of the Lamb, BALL x PIT and Inscryption knows how to ride a news cycle — and All Army Attack gives it a demo next week and a full release in 2027 to talk about.

All Army Attack Gameplay: Cards, Mutations and Armies of Hundreds

Under the joke, All Army Attack is a serious pitch for the auto-battler crowd. You play the Commander, recruiting unique troops and artillery from a vast pool of cards, defeating enemies, and spending the resources you earn to develop powerful new units and draft in massive reinforcements. The official overview promises armies that scale into the hundreds of units in a fast-paced loop, with awesome bosses waiting at the end of each run. Battles are automatic once your army is placed, so the strategy lives in the drafting: which cards to take, which troops to sacrifice, and when to gamble everything on one more fight.

• Fight or Flight: sacrifice or preserve troops strategically to maximise income from every encounter.
• Special Ops: different characters and maps each have their own unique card pools, so every run mixes and matches in new ways.
• Home Base: spend earnings on meta-progression between runs — build up your town, strengthen bonuses and unlock new content.
• Customisation: freely modify cards and units, or craft and mutate every individual soldier for wildly different builds.
• Demo: playable November 16 to 23, 2026, during Steam Auto-Battler Fest.

Customisation is where the game tries to stand out. You can modify cards and units, craft and mutate every individual soldier, and explore combinations between characters, factions, cards and battlefield setups to build devastating armies. Between battles, the Home Base lets you develop things at your own pace — build up your town, strengthen bonuses, unlock new content, or even put hats on your characters. It is the progression loop that keeps auto-battler players coming back for one more run.

All Army Attack Release Date, Demo and Steam Details

All Army Attack launches for PC via Steam in 2027, with no more specific date or price announced yet. The Steam listing is live now and shows support for 10 languages, including English, Japanese, Korean and both Simplified and Traditional Chinese. The first hands-on chance comes soon: an exclusive demo runs from November 16 to 23, 2026, as part of Steam Auto-Battler Fest. Neither Devolver nor BlackLight Games has said whether progress from the demo carries into the full game, so players trying it next week should treat it as a free preview rather than a head start.

No console versions have been announced, so for now this is a PC-only reveal. That fits Devolver's history — Steam is where the publisher generates the overwhelming majority of its revenue — and it also fits the timing, with the demo arriving in the same month as GTA 6's console-only launch. While Rockstar's game is not on PC at launch, Steam traffic around November 19 will be enormous, and Devolver's demo lands right in the middle of that attention.

Why the All Army Attack Reveal Worked

The reveal worked because the joke and the game reinforce each other. The AAA tease was funny enough to travel on its own, but it only matters if the game underneath is worth playing — and a large-scale roguelike auto-battler with card drafting, unit mutation and home-base progression is a genuine pitch to one of Steam's most active genres. If All Army Attack's demo lands well during Auto-Battler Fest, the punchline will be forgotten and the game judged on its own armies.
