Microsoft is taking one of its most popular and recognisable game series to a rival console for the first time.
Halo, a sci-fi shooter fronted by the armour-clad Master Chief, is heading to PlayStation 5 next year, something that would have been unthinkable for gaming fans when the title first launched in 2001.
A remake of the first game Halo: Combat Evolved has been announced for Microsoft's own Xbox hardware, as well as for Sony's PS5, under the name Halo: Campaign Evolved.
It will also launch on PC, and will be playable on mobile phones and tablets through Microsoft's cloud streaming technology.
It's the latest sign Microsoft is moving away from the traditional approach of console makers keeping their own franchises and characters as exclusives.
