Could be interesting if it's done right (with MP and all). Gameloft has shown that first person shooters can and do work on iOS, and Microsoft generally puts a lot of care into their iOS games, so I'd imagine this could play fairly well, if it's real.
I don't know, this post refers at the "Reclaimer Saga" still as Trilogy, even if it was posted after Microsoft announced that it's not a trilogy anymore.
I mean, if he doesn't even get public informations right, I don't really trust his source. :lol
That said, never played any Halo,I just read that news once and didn't care much, so I might be wrong.
As much as I'd love to believe this, I just remember a few weeks ago when a gaffer posted all about how Retro was working on a new new franchise, Mario Kart 8 would just be a MK7 port, and Mario Retroverse would be announced.
Now this Halo stuff definitely sounds 1000% more likely than that stupid Nintendo e3 "leak", and all that Steam registry stuff makes it more likely still, but I'll avoid getting hyped.
Took me years to stop getting hyped about Half Life 3 rumors, so this should be a lot easier, haha.
But goddammit do I want to play Halo 3 in HD 60fps on my PC (or Oculous Rift in the future!). Looooooove that game!
