As you know, every month, Microsoft gives away four games to everyone that has a current Xbox Live Gold account.
If you only have the newer console, it's still a good practice to grab the 360 games, as they're now playable on your Xbox One.
This game will be available from June 1st until June 30th.
However, once you get past the lackluster attempt, it's a pretty fun game with a huge world to race in.
It's a hardcore 2D platformer that takes you back to the days of playing on the original NES.
And as a free title, I highly recommend getting it while it's free.
