Remember that one time when Halo 3's coding was leaked and most of the stuff on that was accurate? Same scenario here. Halo: Reach ALL weapons, characters, vehicles... Seems legit to me.
Well, some of it is wrong, I'm pretty sure there is Stalker for Spartans. And some of the equipment probably explains some obvious in-game deficiencies and should satisfy some players. If it is indeed legit.
Yeah, I'm not sure if that was omitted on accident or purposely in the code, but the legitimacy of this does come into question, which is why I just now dug up some actual posts from the Halo: Reach thread on NeoGAF and they seem to believe it's accurate.
I already saw some stuff from this posted elsewhere on Forge Hub. Looking at all the gametypes, many of them seem to include something where you would spawn then immediately get into a vehicle. Especially for dogfight, is it possible people might spawn into a vehicle as a class? Anyhow it looks like they have expanded the game to include more of the stuff that's just for shits and giggles than the strictly competitive stuff of Halo 3. I really hope this is all true.
