When the chief took down that Promethean knight in the E3 demo, his visor instantly marked the gun that the knight dropped as “LightRifle”…same thing for the “Scattershot”, so how did the database inside of Chief’s suit that has the name and reticle type for all UNSC and Covenant weapons, immidiatly recognize the name and type of reticle of those forerunner guns?

She’s been inside Forerunner Computers before. She recognizes Forerunner tech. Heck, Sentinel Beams are Forerunner weapons so we’ve seen some before.
Either it was just for show.
Or maybe Cortana knows, since she has been in contact with numorous forerunner artifacts and systems?
Or maybe its for gameplay reasons…

Sergeant Positive aren’t you?
Precursor magic. I’m callin’ it.
When Chief picked up the Light Rifle in the demo, Cortana actually said: “I recognize this design, it’s Forerunner”. So yeah…
According to 343i, the E3 video is actually a third of the way through the game, so it would imply that MC has already been introduced to the new weapons.
