The Armour of Horus was one of the artefacts required in the ceremony to summon Horus to defeat Set.

The Armour consists of a breast plate, gauntlets and greaves. At some point, the Armour fell into the hands of Cleopatra. She realized the Armour's significance and had it brought to Alexandria. In 1999, Lara searched around Alexandria and found all of the Armour in various locations. She eventually reached the Temple of Horus and conducted the ceremony to summon Horus. However, the Armour and statue of Horus was destroyed by Set's swarm of locusts before the process was complete. The Amulet of Horus fell into the surrounding water.
