'''Rex''' is an [[Easter egg]] that has appeared in ''[[Halo: Combat Evolved]] and'' ''[[Halo 2]]''. The egg takes the form of the word "Rex" written on a level's scenery. It was added by [[Bungie]] programmer [[Tyson Green]] as a reference to his username "Ferrex".

==''Halo: Combat Evolved''==
===The Maw===
The word "''Rex''" can be found in the level ''[[The Maw (level)|The Maw]]'', written on a wall in [[blood]].

#Proceed normally through ''The Maw'' on any difficulty level, until you get to the huge [[M12 Warthog|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''.

==''Halo 2''==
===Outskirts===
On ''[[Outskirts]]'', the word ''Rex'' is spelled in rocks with a pool of blood and a [[Covenant]] [[Energy Sword]] is [[Outskirts Energy Sword|sticking out of the ground]]. In ''[[Halo 2: Anniversary]]'s'' remastered graphics mode, ''Rex'' is spelled out in shotgun shells.

#Get to the 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. ''Rex'' does not appear in [[Co-op]].

===The Great Journey===
On top of the control room in the level ''[[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 {{Pattern|Anskum|plasma grenade}}s, a {{Pattern|Karo'etba|Ghost}}, and you have the [[Sputnik Skull]] turned on. A video of how to get it can be found [http://www.youtube.com/watch?v=jOhuYlhRgBE here]. However, with the addition of the Acrophobia skull in Halo 2: Anniversary, reaching this easter egg is very easy, as you simply fly to the top.

==Trivia==
In ''[[Halo: The Master Chief Collection]]'', finding the Rex on ''The Maw'' will unlock the [[T-Rex]] achievement, while finding the Rex Sword in ''Outskirts'' will unlock the [[Rex Sword]] achievement.
