Halo Infinite Campaign Network Co-Op Preview

343:

We all remember the first time we played a Halo campaign co-operatively.

Once upon a time, two cryo tubes opened aboard the UNSC Pillar of Autumn and you escaped onto the surface of Alpha Halo together, accidentally meleeing your partner in the back as the level began (just me, huh).

Giving the Covenant back their bomb was a team effort; your road to Recon was a path forged together through the unfinished structures of Installation 08 and the cityscape of New Mombasa. You did not fall on Reachnor to the esoteric shores of Requiemalone, and the Mjolnir-armored boots of the legendary Blue Team and Fireteam Osiris were filled with those of your friends.
