It's been weeks since I've visit the Halo forums, and during that time I have been playing Destiny. I noticed that every week there would be weekly events such as: Story, strike, and raid (I'm excluding PvP, because Halo 5 already has that). So I thought "what if Halo 5 had that". This is what I came up with.
Weekly/monthly story missions: Every week, or month there would be a miniature campaign (the size of ODST) you play as your spartan, and you are given an objective to complete by none other than Palmer. These campaigns will be diverse, fun, and would give lore. Rewards vary, Easy:100 reqs, Normal:1000 reqs, Heroic: exclusive gear (random), Legendary: Full exclusive armor, and a gold tier req pack.
Firefight: This is basically like normal firefight. Choose a game mode, map, and survive. Except now you can play as Osiris, Blue, mix the two teams, or play as yourself with either team, and there is the option to raid a Promethean, Covenant, or insurrection strongholds with bosses being Scarabs, to guardians, etc.
Planet struggle: This is an open world experience. Every month a new planet is chosen to defend.Players must defend the planet, and search for enemies to kill. The top 100 players will be sent to a ship, and must destroy it. The player that destroys the ship, and the top 20 players will be given exclusive rewards that show just how Badass they are.
I know that this most likely won't happen, and yes I'm recycling a post that I made earlier, but this is what would bring Halo up there.
