Leaker @Mr_Rebs claims that Halo: Combat Evolved may receive a content update, with Firefight and Theater modes in the pipeline. However, he also stated that recent layoffs could lead to the cancellation of some plans, leaving it uncertain whether these two modes will be implemented.
According to @Mr_Rebs, Halo Studios currently has a team of about 30 people led by Pierre Hintze. The team's current tasks include organizing Halo Fest and preparing the upcoming update for Halo: Combat Evolved.
Firefight mode centers on cooperative play against waves of enemies. Theater mode allows players to replay matches, record clips, and view games with a free camera. Neither feature was available at launch.
@Mr_Rebs further claimed that this team has no connection to Activision or future work on the Halo series, and predicted that Halo Studios might disappear entirely in the future. Statements regarding team arrangements, future directions, and game updates have not yet been officially confirmed.
