The five remaining subjects from the Echo 49 facility race through the forest, mercilessly pursued by the facility guards. While Maven leads them ever deeper into the unknown, Lieutenant Harless lays his trap for Orion.
One of the subjects lies dead; and the rest broken. Lieutenant Harless has activated the control chip inside Orion, leaving the subjects unable to flee. And all too soon a traitor will be revealed.
Orion attempts to use the tracking chips to trick the guards, resulting in a confrontation with Private Nyx. Elsewhere Vela forces an imprisoned Maven to take the remaining subjects to the bunker - with Lieutenant Harless in close pursuit.
Orion and Harless have their final battle in the ruins outside the forest; while Maven leads the Echo guards into the secret bunker. Only two subjects will survive the revelation of Echo 49.
