All Army Attack announced as Devolver Digital's first AAA game for 2027

Devolver Digital and BlackLight Games have announced All Army Attack, a large-scale roguelike auto-battler heading to PC via Steam in 2027. The game turns the usual small squad into a ridiculous, screen-filling army of animals and plants, with battles built around positioning, upgrades and a steady stream of new recruits. ¹

The Steam listing describes a run-based structure in which players assemble armies, choose from card pools tied to characters and maps, and adapt their force as each fight escalates. Alongside the battles, there is meta-progression and a town-development layer, giving successful runs a longer-term purpose rather than treating every defeat as a total reset. ¹

The central hook is scale. Instead of controlling one hero through a conventional action game, All Army Attack asks players to manage a mass of units spilling across the battlefield. Its presentation leans into the chaos: rival formations collide in crowded arenas while players try to build combinations strong enough to survive the next encounter.

Devolver is presenting the project as its first AAA game for 2027, although that is the publisher's own framing rather than an independent production classification. The announcement is therefore best read as a statement of ambition, not a promise about budget, scope or final quality. The Steam page currently lists the game for PC, but does not give a final release date, price or system requirements beyond an operating-system entry marked TBC. ¹

A playable demo is planned for Steam Auto-Battler Fest, which runs from 16 to 23 November 2026. That gives curious players an earlier chance to test whether the enormous armies make the strategy deeper or merely make the screen busier. ¹

What to watch

The unanswered questions are the important ones: how much control players have once an army reaches full size, how varied the card pools and maps are, and whether the town layer meaningfully changes later runs. The absence of a firm launch date also means this remains an announcement rather than a near-term release story.

Our opinion

All Army Attack has a clear, properly Devolver-sized hook: build an army so large that the battlefield becomes the spectacle. That is enough to make the demo worth watching, but the concept will live or die on readability and meaningful decisions. If the player can still see why a formation succeeds or collapses beneath all those units, the chaos could be the point rather than a distraction.
