Rex is an easter egg that has appeared in Halo: Combat Evolved and Halo 2 . The easter egg takes the form of the word "Rex" written on a level's scenery. It was added by Bungie programmer Tyson Green.
Halo: Combat Evolved RexEdit
- Proceed normally through The Maw on any difficulty level, until you get to the huge Warthog jump/free fall.
- At the ledge, drive the Warthog to the right, so you land on the side of the floating platform.
- Enter the corridor and look to the right side. Spelled out in blood is the word Rex; on the other side, there is a bloody swastika.
Halo 2 RexEdit
- Get to the rooftops and go to the area where the Jackal Snipers and Drones are.
- Keep going until you reach the building with two snipers in it.
- Turn and there should be a room in a building you can jump into, the Rex is in there, along with the sword. Keep in mind though that the Rex is not always in there and when it is, the sword may not have infinite energy. Also, Rex does not appear in Co-op.
Great JourneyEditOn top of the final tower in the Great Journey, the word "REX" is written in Flood blood. It seems that the only way to see this particular Rex is by using Dev Cam mode, unless you have a pile of Plasma Grenades, a Ghost, and you have the Sputnik Skull turned on. A video of how to get it can be found here.
"Halo: Combat Evolved Anniversary" RexEdit
On The Maw, the REX also appears in Halo: CEA. However, rather than a bloody swastika, there is simply a splotch of blood on the opposite wall. If you go into original mode, the whole Easter Egg is missing. This was likely done to prevent controversy over the swastika.
