Dan Gniady is credited as the designer of Halo: Campaign Evolved in Wikipedia’s infobox.
The remake is developed by Halo Studios and published by Xbox Game Studios. It rebuilds the campaign of 2001’s Halo: Combat Evolved in Unreal Engine 5 while adding redesigned missions, new weapons, updated vehicles, expanded mechanics, and freshly recorded cinematics.
Gniady’s design work is associated with the team’s effort to preserve the original game’s scene structure and recognizable identity while modernizing its presentation and gameplay. He is distinct from Max Szalgor and Greg Hermann, who are listed as the game’s directors.
A common mix-up is confusing the designer credit with the directors’ credits or with Bungie’s original Combat Evolved designers. Campaign Evolved is a later remake made by Halo Studios, not the 2001 Bungie production.
