 Warhawk was first announced to the public in May 2005 , with a working build shown at E3 in 2006 . This version was the first PlayStation 3 title to be shown with the newly announced Sixaxis motion sensing technology . In February 2007 , it was announced that the single player element of the game was to be pulled . This was due to concerns Incognito had over the quality of the single @-@ player campaign , particularly when compared to the multi @-@ player modes . Dylan Jobe , the game 's director , stated , " If we were to continue down our single @-@ player / multiplayer approach , it would have resulted in not as good single player or not as good multiplayer " . The extra development of the multiplayer mode was used to improve existing elements such as in @-@ game communication , and to implement new features such as On Demand Split Screen , whereby players can easily enter split screen mid @-@ game . Split screen can only be used in battles that allow it . Only unranked servers have the ability to have it and even then , it is an option whether or not the host wants it on or off . It was also revealed at the same time that Warhawk would be made available for download over the PlayStation Network .
