I don’t have a name for it but I think this would be a good idea for a halo celebration for the aniversary.
in this DLC theres 1 multiplayer map, and 2 firefight maps,
The Map is a remake of terminal called, Subway.
the firefight map is Lost Charity
Here a team of spartans have gotten on High charity and are now fighting for there lives. will they survive.
The other takes place in a small zoowhere randomly one of the exsibits open releacing eather
1 thorn beast
or 1 gueta (being a female (campain) or male (a little larger with plates on his back)
thats just and idea for a dlc but I think it would work in any future halo game
