I hope it's Halo 3 as it is for PC, I don't want them touching it / changing anything about H3.
Possible AMD leak of Halo 3 PC or H3A?
buss a NUT
Been sayin it for over a year now. H3A will come out winter of 2017. The reveal will be at E3 most likely. And it'll be in the H5 engine :'(
I think it will just be a brand new engine and they will use it for Halo 6 too.
