1st Logo (November 15, 2011-2021)
Logo: A sparkle reveals a metallic shape. A metal piece sweeps across the screen, revealing "343 INDUSTRIES" in the Handel Gothic font. The "4" tilts a bit.

FX/SFX: Rather cool CGI.

Music/Sounds: Some dark toned mechanical sounds, presumably a dark whoosh. The Blu-ray releases of Halo: Nightfall and Halo: The Fall of Reach have the logo in a low tone.

Availability: Currently seen on the Halo games starting with Combat Evolved Anniversary. Also seen on other Halo projects such as Halo 4: Forward onto Dawn.
