Shielded dead Elite
From Halopedia, the Halo wiki
Template:Ratings To see a Dead Shielded Elite, you must play Halo: Combat Evolved, where there is a glitch that allows you to see an Elite's shield, even when it is dead.
To do this, start any level and play through it on any difficulty, until you reach an Elite. Do not attack him, instead, wait until you get behind him, then beat him in the back, so that he'll instantly die. Now that you've done that, shoot his corpse. It should flicker like the Elite's shield isn't disabled. This works with all types of Elites, even Zealots. It doesn't work in Halo 2 or Halo 3 though.
The easiest way to see this glitch is to start Assault On The Control Room, and play until you get to the bridge. There is an Elite on the lower level (usually a major). Simply catch him off guard and hit him in the back and shoot his corpse to see the glitch.
