Backward Compatibility program has reached 300+ titles today with Bioshock trilogy being available to all Xbox users. Phil Spencer, head of Xbox department at Microsoft went to Twitter to thank all the players for this massive achievement saying -” Now over 300 back compat titles. Nearly 50% of XB1 owners playing BC games is great to see. Thanks for supporting the program.”
That is an impressive number Phil just revealed to the public. BC was unveiled back at E3 2015 with a massive positive response from fans and was launched back in November 2015 with a few titles. A year later, over 300 are available to all Xbox One users.

Now over 300 back compat titles. Nearly 50% of XB1 owners playing BC games is great to see. Thanks for supporting the program.
