Derrick awakes in a device designed by Stefania, and it is revealed that the device was used to piece together Derrick's fragmented memories. Derrick finds himself in a dystopian future controlled by the T'lan. A group of Terminus 4 scientists explains that Derrick will experience the "pendulum effect", swinging him back in time to shortly before he left. This will allow him to relive events, and hopefully, prevent the rockets' launch. Traveling through the complex to reach Glen, Derrick finds Alex. They meet Glen, who reveals that although they failed to stop the launch 15 years before, they had time to further refine T'langen. The "ultra accelerator" injection gives Derrick the power he needs to change the past. As the pendulum effect begins, Alex accompanies Derrick to the present, knowing she will be killed by Solus. They are separated in the pendulum-effect tunnel and will arrive at different times. Derrick arrives moments after Alex is captured by Solus, while Alex is sent to the recovery facility at the moment where she rescued Derrick, facilitating Derrick's journey at the beginning of the game.
