The player and Desmond then go to the light house to finish Calvert off, and when they reach the chamber where his brain is he turns out to be almost completely defenseless – the only robots guarding him are Protectrons, and most of them don’t even work! Here, Calvert tells the player to kill Desmond for no reason in a last attempt to stop his rival, and even if you are foolish enough to believe this and do kill Desmond, Calvert still turns on you afterwards and tries to kill you, but still has next to no working defense systems and is then killed easily as usual.
