Surely it sounds very greedy to expect 343i to produce two separate campaigns, doesn’t it? But what if a secondary campaign proved to be incredibly beneficial to the fiction Halo universe. Despite the fact that Halo 2 was criticized for having a duel campaign, it’s still lauded for heavily expanding the role of the Covenant and Halo lore in general. And that’s what i’m getting at.
What if Halo 5 were to have one main campaign based around the events of John-117, and had a separate secondary campaign for someone like Thel 'Vadam? It sounds perfect to me. As I said Halo 2’s storyline was criticized for being confusing and taking us away from the Chief, and Halo 3’s was also criticized for removing the Arbiter’s status as a playable character, and hereby omitting and interesting part of the storyline.
Halo 5 could escape these issues by seperating their tales into two different campaigns. For example:
John-117: I predict that Master Chief’s campaign would be based around the continuing skirmish with the Promethean forces and their allies, the Covenant Remnants. It would also feature the release of Flood and the discovery of the Precursor’s role in their creation. The game would end with promises of the Precursor’s return, to see if humanity truly are capable of overseeing the mantle.
Thel 'Vadam: While the Arbiter’s campaign should be based largely around his war with the Covenant remnant over Sanghelios, as well as other alien planets. Perhaps the threat of the Flood will also come into place. And later on, the Arbiter might discover something amazing which could turn the tides of the entire war.
I’m not saying that they can’t overlap at time, because I think it would make sense if they do. It’s just that I don’t think most players like being taken out of the ‘boots’ of one character, only to end up playing as someone else who’s unrelated elsewhere. I think two unique campaigns could resolve that problem.
There’s also the fact that I think the Arbiter’s plot-thread is too large to tell through something like Spartan Ops or the books; we need a new campaign told from his perspective. With the addition of a campaign from his perspective, we could also expect the return of the Elites into multiplayer.
TL;DR - I propose that we create two separate campaigns in Halo 5. One would be told from the Chief’s perspective, and another from the Arbiter’s perspective. So what does everyone think of my solution?
