I think it would also be interesting to have some of the star cast members of Call of Duty have a pseudo crossover into Halo Infinite as a chain of side-missions where you go to rescue captured ODSTs.
Imagine it. You are exploring Zeta Halo and approaching a beacon. All of a sudden you hear a familiar voice come in over the radio -
“This is Captain Price of the One-Hundred-and-Forty-First battalion of helljumpers! We are broadcasting a beacon to a data-drive that contains our present location under heavy encryption. Please respond, I have wounded! This message will repeat.”
Upon arriving to the location of the beacon, you find a LOT of dead banished with evidence of the cause of death being sniper fire from multiple angles. And then Elizabeth (what I hope The Weapon ends up calling herself) announces that there is someone trying to open comms with them over a UNSC signal.
Familiar Voice - “Well I’ll bloody be… That isn’t who I think it is, is it?”
Chief - “This Master Chief Petty Officer John-117. Identify yourself.”
Familiar Voice - “I’m the Lieutenant of the One-Hundred-and-Forty-First battalion. Callsign is Ghost sir. My current location is up high at your four o’clock. See the glint?”
*Chief looks up to see a glinting light reflection up high on a ridge.
Chief - “I copy your location Ghost. What’s the status of your battalion?”
Ghost - “Meet me up here and I will give you the details sir. Comms aren’t safe.”
*players go up to meet with Ghost on the ridge.
Ghost - “You sure are a sight for these dead eyes Master Chief.”
Chief - “Where are the rest of you men?”
Ghost - “Most of the battalion was lost with the UNSC Infinity. A few squads made it onto the ring during the chaos. And those of us who aren’t present have been recently captured by the Banished… or worse… made the ‘guest of honor’ at the dinner table.”
Elizabeth - “Oh no.”
Chief - “How many are missing?”
Ghost - “Price, Gaz, Soap, Roach, Farah, Kyle, and Yuri are MIA. Sandman, Allen, Ramirez, and I are all that’s left that we know of. We have been picking off banished who have been investigating the beacon. I know you might be a bit busy with other operations, but as it stands right now we are too busy defending the beacon that the Captain left behind to risk sending out a man or two. Could you help us in regrouping?”
Chief - “I’ve got time. Do you have any leads?”
Ghost - “Less of a lead and more of a hunch really, but there is a Banished outpost upspin that we lost Kyle and Yuri during a supply raid. That would be the best place to start.”
Chief - “Agreed.”
Would make for an interesting side-quest line that could reward players with ODST-themed armor pieces for multiplayer customization. Especially when they eventually add in an ODST Armor Core like Helljumper Gen-3 somewhere down the line.
Also Sam Witwer would also be a great choice for a Private of the Infinity Security teams who had expected to live a soldier’s life off of the front lines, only to be shoved into the Banished occupied Zeta Halo as someone who feels not up to the task but eventually grew to be someone who now is more comfortable in this hostile environment.
