Shielded Flood Carriers, modded into Waterworks.
Shielded Flood Carriers are a varient of Flood Carrier Forms with Jackal Personal Arm Shields. These were tested by Bungie, and their unfinished forms have been found buried in the Halo 2 disc, but they have not been included in any actual game.[1] The behavior of the Shielded Carrier Form is identical to the unshielded varient, the sole difference being that it is harder to shoot.[2]
