<P> In the film The Lord of the Rings: The Fellowship of the Ring some Uruk - hai are seen being birthed full - grown from what appear to be sacs in muddy pits . (This is used as a device to allow Saruman to build his army practically overnight, as opposed to taking the time to breed his "improved" Orcs through more conventional means .) </P> <P> In The Rise of the Witch - king, an expansion pack for The Battle for Middle - earth II, the Angmar faction uses "Gundabad Orcs" as ordinary foot soldiers, referring to their capital of Mount Gundabad . Like the Goblins of the Misty Mountains, they sometimes ride Wargs into battle . </P> <P> In the video game Middle - earth: Shadow of Mordor, the Orc hierarchy in Mordor plays a pivotal role in both the story and gameplay . </P>
