I think that they'll only include a Prophet and a Arbiter if they find a good place to put them. And don't go saying something like "they didn't have an Arbiter at that time" or "prophets didn't go onto the battlefield" because the point of a mod is to change stuff, right? That means that they don't have to stick to the story 100% Anyways, this mod will be great, and I hope that it won't become the new SPv2 (a.k.a no hordes of fanboys).

That's a very old picture that's just showing that they converted the bipeds from Halo 2 to Halo 1.
