Microsoft has announced that four new Xbox 360 titles are now backwards compatible with the Xbox One.
The titles are Alan Wake's American Nightmare, Trials HD, LEGO Batman and Sam & Max: Beyond Time and Space. If you don't own Alan Wake's American Nightmare and are planning to get Quantum Break, you can get the game for free if you pre-order Quantum Break on the Xbox Store. Red Dead Redemption, Left 4 Dead 2, Halo Wars, Castlevania: Symphony of the Night and Tekken Tag Tournament 2 were made available a few days ago by accident, with Microsoft later removing them because the games still haven't been fully tested. This means that these titles could be coming next.
