Peggle 2 released today! Halo Spartan Assault comes to Xbox One on 12/24 for $14.99. It'll be $4.99 if you've bought the Windows Phone 8 or Windows 8 version before 12/15. It's currently $6.99 so you'd end up saving about $3.

Also, both Peggle 2 and Halo SA have full 1000 GS. Perhaps a new thing and all games get the full score?
