Halo: Spartan Assault has gone universal: you can buy it once on one Windows-powered device and download it on your others. As we noted yesterday, Microsoft started accepting submissions for universal apps , and combined with the new unified pricing tiers and [universal app development] and automated certification we're starting to see the first universal apps appear. A notable entrant: Halo: Spartan Assault .

Nothing about the game itself has really changed — it's still the same great touch-driven strategy game that we know and love, but now that $4.99 price tag is good across your own personal Windows ecosystem. Buy it on your Windows Phone, download it for free on your Windows PC. Or do the opposite. The Windows Store and Windows Phone Store don't care.

Apps and games that are certified universal are annotated with a new "Made for Windows Phones and PCs" icon and text. Let us know in the comments what other apps you see that have been updated as such.
