Bungie has admitted to using artwork without credit in Marathon's alpha build, following accusations by artist Antireal.
Antireal pointed out assets in Marathon's alpha that closely resembled her designs from 2017, including triangular V graphics and boxed icons.
In response, Bungie acknowledged the unauthorized use of artist decals in the game, stating that a former Bungie artist included them in a texture sheet.
Bungie is conducting a review of in-game assets by the former artist and has reached out to Antireal to resolve the issue, while her support community has donated through her Ko-fi page.
