Bungie announced the follow-up to Pathways, a new 3d action shooter called Marathon, in a press release entitled MARATHON TAKES TEXTURE MAPPING INTO SPACE

They had shown an early version of the game, later dubbed Marathon Zero, at the MacWorld show in San Francisco in January of that year, but later revamped it entirely.

Sadly, Bungie expected the game to ship within a few weeks, but delays forced the game's release until December.
