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. However, it is the old model from Halo 2. 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 the default blue like most Flood when the body is destroyed.
