Back in late July, it was announced that 2019's Terminator: Resistance would be getting an upgrade for Xbox Series X and Xbox Series S - firstly in the form of a free upgrade on September 27th for the base game and Infiltrator Mode, and then in the form of a (paid) "Complete Edition" featuring all previously released content on October 27th.
It's the latter that developer Teyon is primarily focusing on today, releasing some new Xbox Series X footage of Infiltrator Mode along with the Complete Edition exclusive "Annihilation Line". You can watch this in the video up above.
In terms of resolutions and frame rates, it's already been confirmed that the Xbox Series X version will run at 4K, 60FPS and the Xbox Series S version will run at 1080p, 60FPS. We also know that if you already own the Xbox One version of the game and you still want access to all the "Complete Edition" content, you'll only need to pay £11.99 / $14.49 as a special upgrade price when it arrives in late October.
There's more information about all of this in a special FAQ section on the Terminator: Resistance website if you're still confused, so be sure to check it out! Hopefully this ends up being a great upgrade when it arrives in the near future.
