Rtas 'Vadum in crashed Flood ship

The Rtas 'Vadum in crashed Flood ship easter egg can be found on the Halo 3 level Floodgate.

When you jump down the hole to get into the Flood ship that crashed, there will be a few dead Ultra Elites lying around. Sometimes one or more will have Rtas 'Vadum's face, in which two mandibles are missing. You can get it infected, too, if you push it down the hole and release some Infection Forms. When he turns into a Flood Combat Form, his armor remains silver, but changes to default blue, like all Flood Sangheili Forms, when the body is destroyed. This is most likely caused because Rtas's body model was the only one of an Ultra Elite, which is why the corpse is identical to him.
