Halo Reach is finally out for the Halo Master Chief Collection on both PC and Xbox One. We don't know yet how it is faring on Microsoft Store, but Steam launch figures are very strong as it peaked at over 160K concurrent players on Valve's platform.

That said, Halo Reach doesn't exactly look very hot even at 4K resolution and 'enhanced' graphics on PC, which isn't too surprising given that it's a port of an Xbox 360 game originally launched in 2010.
