Robbie appears in both TA 1 and TA 2 in cutscenes as a Melchizadek weapon's specialist and engineer. He does not play much of a major role until TA 3, in which he has engineered a power suit known as The Anubis V, which is unlockable as a drivable vehicle in multiplayer. Robbie travels with the team to Atlantis, and through the portal, in which he confronts the Core, and battles it before his suit is destroyed. Davian then tosses him The Eye and Robbie catches it just as he is consumed by The Core. Thanks to Robbie's efforts, The Harbingers were able to kill The Core and stop the Spawn invasion.
