The final confrontation with Deathshead involves his personal, heavily armed robot. This boss has multiple phases. In the first phase, focus on destroying the armor plates on its arms and legs using heavy weapons like the Laserkraftwerk or rocket launcher. Once the armor is gone, target the exposed components. Deathshead will also attack you directly from the cockpit. In the second phase, the robot becomes more aggressive. Utilize the environment for cover and pick up any available heavy weapons. The key is sustained damage and avoiding its powerful area-of-effect attacks. use grenades.
