Xbox head Phil Spencer took to Twitter to claim that half of Xbox One owners play Xbox 360 backwards compatible titles on their current-gen system.
Now over 300 back compat titles. Nearly 50% of XB1 owners playing BC games is great to see. Thanks for supporting the program.

The most recent titles to hit the backwards compatibility program are Bioshock, Bioshock 2 and Bioshock: Infinite.
