Bungie's blockbuster FPS Halo: Reach is the latest title to be added to Xbox Live's Games on Demand service, Microsoft has announced.
It's available for download from today but you'll need to scrape together £49.99 for the privilege.
As a quick comparison, Amazon are currently asking £25.48, Play want £24.99 and GAME want £34.99. All throw in a free plastic case and bits of staple-bound paper to boot.
The Xbox 360 exclusive shooter launched more than six months ago back in September 2010, winning a 9/10 from Eurogamer.
