Here's the multiplayer portion of that leak.
Until we see BTB, this might actually pan out.
Halo War arena is basically Arena from Halo 5. I think the beta had static spawners.
From what we have heard, BTB seems to be getting something new and at least bigger according to Kamp, and I'm not past 343 adding loadouts and shit into the game because they have to fuck something up.
Loadouts on a 32v32 is not a problem to me...you are basically taking it from an arena shooter to something more akin to battlefield...having control over your loadout is good in that situation
Man i hope half of that leak is true
