As a 4X turn-based strategy game set in the Warhammer 40,000 universe, you lead one of four unique factions—Astra Militarum, Space Marines, Orks, or Necrons—in a brutal fight for control of the planet Gladius Prime. The core loop involves exploration, expansion, resource exploitation, and military extermination, with each faction possessing distinct tech trees and units. Unlike typical 4X titles, this game removes diplomacy, focusing solely on tactical combat and total domination. Released in 2018, the game has since received numerous expansions adding more factions and content, offering deep strategic replayability on PC and Linux.
The narrative centers on Gladius Prime, a world whose archaeological discoveries inadvertently triggered a catastrophic conflict. Players step into this environment of terror and violence, commanding one of four distinct factions vying for dominance over the planet’s vital resources. The atmosphere is one of constant warfare, where every decision regarding resource management and military deployment carries significant weight.
As a turn-based strategy title, the gameplay loop involves managing cities, researching technology, building armies, and engaging in tactical combat against rival forces. Each of the four initial factions—the disciplined Astra Militarum, the zealous Space Marines, the savage Orks, and the ancient Necrons—offers a unique strategic experience. This uniqueness extends to their specific technological trees, specialized units, and powerful hero units.
Combat unfolds on a hex-based map, emphasizing tactical positioning and unit synergy. Beyond direct conflict, players must secure resource nodes scattered across the map to fuel their war machine and technological advancement.
The primary distinction lies in its complete dedication to military conflict and the absence of traditional diplomatic mechanics often found in other 4X games. There is no negotiation or alliance-building; the objective is singular: total domination through military might. Furthermore, the game features a challenging Artificial Intelligence designed to provide a robust single-player experience, alongside options to compete or cooperate with other players online.
Since its initial launch, the game has received substantial additional content. While the base game features the four core factions, there are currently 11 downloadable content (DLC) packs and 6 major expansions available, which introduce new factions, units, and gameplay elements to the conflict on Gladius Prime, significantly increasing the variety of strategic choices available to returning players.
This strategy title is available on PC (Microsoft Windows) and Linux platforms.
