I should outline the main plot points: Introduction to the mission, encounter with the gatekeeper, installation process, overcoming obstacles, climax where the installation is successful or failed, and a resolution. Make sure Lara's skills are showcased, like problem-solving, combat, or navigation. lara+the+gatekeeper+install
