Rebellion has confirmed that Rogue Trooper Redux will be releasing on October 17th for PS4, Xbox One, and PC, with the Switch version to be released at a later date. In addition to the release date some new footage has been released that shows the original Rogue Trooper side by side with the Redux version of the game.
As you can see from the footage the Redux version has much more detailed character models, with the environments looking a lot brighter compared to the almost washed out look of the original game.
