ReCore was announced at this years E3. In the debut trailer for the game, a female protagonist is shown in a vast desert, accompanied by a robotic dog with a glowing sphere in its stomach. As the pair explore a vault, they are attacked by robotic enemies. The protagonist has a grappling hook that she uses to remove the cores from the enemies, causing them to collapse, but when the pair are about to be overwhelmed, the robot dog self-destructs to destroy the enemy robots, leaving behind its core. The protagonist collects the core and finds a humanoid robot in the vault and inserts the core into it. The robot comes to life, and the two appear to recognize each other again.
