Towards the end of production on Halo: Campaign Evolved, a few of the in-house artists were asked to finalize and build out some of the extra missions and their associated maps. This mission, "The Most Dangerous Game", was a collaboration between our partner teams and our own internal art team.
I spent much of the time kitbashing and defining the look of the various Covenant gates, as well as the Temple, and various playable spaces.
Credit to my colleagues, Ned Gasorntip and Tuan Tran for the hard surface and additional world building work in this map, as well as to Nate Castronovo, Chris Matthews and Donnie Taylor for Art Direction.
