Sebastian Gosztyla, a programmer for such games as Guilty Party and Avengers Initiative, wanted to make games less escapist and more interactive with other human beings. After experimenting with different gameplay styles he has come up with Dual.
The game involves two players and each of their screens make up half of the play area. Players fling missiles at each other and attempt to doge them by physically moving and tilting their phones. The game communicates between phones using bluetooth or wifi on the iPhone and Android, which makes it a great play-anywhere-anytime game.
There is no set release date, but Sebastian Gosztyla is hoping to make Dual available sometime near the end of summer.
