While speaking with OXM, Bungie's own Brian Jarrard said that they regretted not including matchmaking in ODST's firefight mode.

"I regret not being able to go back and make Firefight in ODST work and have match-making," he told us. "I think we would have loved to have done that. We've heard it from the fans, we've heard it from the press. It's definitely something we'd have loved to be able to do but we didn't have the scope on the project. We didn't have the time.

"We accomplished a tremendous amount, but that's probably the reason ODST isn't being played as much right now as we'd like. It has had a shorter lifecycle than any of the Halo titles before. But Reach is our big chance to make up for some of those things. "
