Halo Infinite Game Modes

Is there any information regarding what game modes will be available in halo Infinite? I did have a look, but all I could find is information on social and ranked team matches. I saw from the E3 demonstration that they are giving a big push to player’s multiplayer character and it would be great to be able to use them in more than one game type.
Will there be anything like Firefight or Spartan ops? Halo Reach was one of my favorite Halo games, because I could use my custom character in everything.
