The second wave of April's original Xbox games have arrived on Xbox One. Following the month's earlier additions to the backwards compatible library, 10 more classic Xbox titles are now playable on Microsoft's current-gen console, plus an additional one if you live in Europe.

This batch of BC titles includes the alien adventure game Destroy All Humans; the military strategy game Full Spectrum Warrior; the motocross game MX Unleashed; and the third-person shooter Mercenaries: Playground of Destruction. Xbox One owners in Europe, meanwhile, get an additional backwards compatible game in the form of Panzer Elite Action: Fields of Glory.
