A Shielded Flood Carrier Form is a Flood Carrier Form equipped with a Kig-Yar point defense gauntlet. They were found buried in the Halo 2 disc, but are not included in any actual game. The behavior of the Shielded Carrier Form is identical to the unshielded variant; the sole difference is that it is harder to shoot them and kill them.
