Shield
From WikiRaider
In Lara Croft and the Temple of Osiris Horus and Isis can use their Shield to defend themselves against all kinds of Enemies and their projectiles. Unlike Totec's Shield in GoL this is an energy barrier that surrounds the player on all sides, protecting him or her even from attacks from behind, but it weakens over time and may fail completely, leaving the player vulnerable to attacks. As before, the other players like Lara or Carter Bell can stand on the shield to reach higher ground by jumping.
Instead of a shield Lara has a Magnetic Grapple she can attach to rings and other players.
