Warhammer 40,000: Rogue Trader is an isometric turn-based tactical role-playing game developed and published by Owlcat Games set in the Warhammer 40,000 universe. The game was released for Windows PC, macOS, PlayStation 5, and Xbox Series X and Series S in December 2023.

Similar to prior Owlcat games (Pathfinder: Kingmaker), Rogue Trader is an isometric role-playing video game, heavily utilizing the d100 TTRPG system from the game of the same name.

The player controls a party of six characters, including their own through ground combat and social interactions.[3] It features a turn-based combat system and an isometric perspective. One of the game's distinguishing features is its emphasis on realm-building, with the player's decisions as a Rogue Trader affecting the rest of the gameplay as they build their space empire.[4] Space combat is also present. The game also supports a cooperative multiplayer mode.[5]

The alignment system allows the player to make Dogmatic choices that are typically merciless but in keeping with the setting's fervent belief in the God-Emperor, Iconoclastic choices that challenge the status quo, or Heretical choices that are Chaos-aligned. These choice radically alter conversation options and equipment availability.
