I would love to see a team action sack mode added to halo 5!! I absolutely love all the non-traditional fun & silly game modes that are in that playlist in the Master chief collection. For those that didn’t play MCC Team action sack is a playlist of casual fun non-traditional games. For example, all swords, gun goose CTF, oddball, etc etc. I know we get a tiny bit of non-traditional game modes on weekend sometimes but I would absolutely love a dedicated mode for team action sack!!
Oh and ninja slayer & stickyball are great too!!! 
Action Sack? Yes, please.
BRING BACK THE SACK!
BRING BACK THE SACK!
BRING BACK THE SACK!
^Exactly!!
Yes please! However I would think that they are waiting until we get some awesome mini-games made in forge, big fan of Action Sack since Halo 3 and Reach!
I think it very well could happen, but probably around forge’s arrival in December! Or sometime after
