Devolver Digital and developer BlackLight Games have officially announced All Army Attack, a large-scale roguelike auto-battler coming to PC via Steam in 2027. The game combines card-based army construction, automated battles and persistent progression, allowing players to command hundreds of animal and plant units against increasingly powerful enemies. A playable demo will be available from November 16 to 23, 2026, during Steam Auto-Battler Fest.
The announcement was made on November 10 alongside the game’s debut trailer and Steam store listing. Devolver Digital also introduced All Army Attack as its first “AAA” game, a playful reference to the three-letter abbreviation of its title rather than a confirmed indication of its production budget.
All Army Attack puts players in the role of a Commander tasked with assembling an unconventional army to confront a cosmic threat. Troops and artillery are recruited through cards, with successful battles providing resources to develop stronger units and bring additional reinforcements onto the battlefield.
Armies begin with relatively small formations but can eventually expand into hundreds of individual units. Players can customize cards, modify soldiers and experiment with combinations of characters, factions and battlefield arrangements to create different strategies across successive runs.
One of the game’s central mechanics involves deciding whether to preserve existing troops or sacrifice them to maximize income from individual encounters. These decisions influence the resources available for future battles, introducing an economic element alongside army composition and automated combat.
Different playable characters and maps also feature distinct card pools, encouraging experimentation with unit combinations and tactical approaches.
Progression extends beyond individual battles through a home base where accumulated resources can be invested in permanent improvements. Players can develop their town, strengthen bonuses, unlock additional content and customize characters with cosmetic items.
The combination of roguelike progression and card-driven strategy places All Army Attack alongside other upcoming PC strategy releases, including Everbrink, a 4X roguelike deckbuilder scheduled for Steam Early Access in 2027.
The upcoming Steam demo will offer a substantial preview of All Army Attack’s gameplay systems. According to the publisher’s official announcement, players will be able to experience the game’s prologue and the Arid Wastes across six progressively challenging difficulty levels.
The demo will include three playable characters, 60 unit types, 25 unit enhancements, 40 treasures and more than 70 cards. Players will also have access to a demo-exclusive Treasure Shop designed to provide additional opportunities for adjusting their strategies.
Devolver Digital says the demo will include an online feature allowing players to challenge friends and compare their armies. The Steam store currently categorizes the full game as a single-player experience, and the publisher has not clarified whether this online functionality will carry over into the final release.
The limited-time demo joins a growing selection of upcoming PC releases offering playable previews ahead of their full launches. Other recently announced projects include Bolt of Whalington, which has a free Steam demo available ahead of its planned 2027 release.
All Army Attack is currently scheduled for release on Windows PC through Steam in 2027. The publisher has not announced a specific launch date or pricing, and the Steam listing does not yet provide detailed PC hardware requirements.
Players can add All Army Attack to their Steam wishlists ahead of the November 16–23 demo period. The full game remains scheduled for 2027, with no additional platforms confirmed.
