- Official description

DEMO-class Mjolnir is an experimental variant of MJOLNIR [GEN2] armor, which was approved for testing on ANVIL Station.

Development history
The DEMO armor was tested at ANVIL Station on behalf of unidentified third parties.

In-game information
The Demo armor set was first introduced into Halo 3's MCC port along with eleven other new armor sets, as part of Season 5. It was never available in Halo 3 for Xbox 360. The set is one of six sets not to have any associated forearm armor.

Production notes
The DEMO armor set was originally created as a useable armor permutation for Halo Online, a cancelled Halo 3-derived multiplayer game developed by Saber Interactive and Innova Systems which was intended to be released exclusively in Russia for the PC. After the game's cancellation in 2016, the armor was one of twelve sets introduced to Halo 3 in The Master Chief Collection as part of the game's fifth season in 2021.
