HALO 5 IDEAS
I think that maybe cortana should be back and that you can play as master chief as he should visit earth and find out about the odst's in new mombasa, reach where he finds out the history of noble team, and new forerunner planet, where there is a halo ring on the outside (like Jupiter its rings)
Brutes and flood should be back as different factions
every single weapon from previous halo's should be back and amplified so they are all equal and not overpowered, but have more varieties of weapons like halo 3.
Able to have equipment, armor abilities and 5 different types of grenades: frag, plasma, spike, flame and pulse but making their rate of explosion more higher and their damage within 1.5-2.5 radius.
equipment as in portable gravlifts powerdrain tripmine etc from halo 3
armor abilities must stay and jet pack must be better or equvalent power from halo reach cuz it just sucks in halo 4
make one map that is massive and that is the same as a battlefield map cuz so on multipayer it can be spartans vs elites slayer with mammoths, elephants, pelicans, shortsword, longswords phantoms scarabs every halo wars vehicle for unsc and convenant so its one big total war on the field so its just massacre everywhere.
game mode for flood vs Prometheans
flood vs spartans
elite vs spartans
slayers
make zombies, spartan zombies and flood in infection playlists invasion must come back
to be continued!!!
