A former Halo developer has commented on the many ideas for new Halo games that were pitched to higher-ups, including one concept that was "really dark."

Kevin Schmitt, who worked at 343 Industries for 12 years, replied to a thread on social media about ideas for Halo games that never got made. Schmitt said the team pitched as many as 30 games that he believed would have "totally worked in the Halo universe."

"Many [single-player] & [multiplayer] ODST-themed ones. Some galaxy-spanning, some more intimate…and one that was really dark. lol," he wrote.
