 There are two ground vehicles , a jeep and a tank , and an armored personnel carrier is added by the Operation : Broken Mirror expansion . There are two air vehicles , the Warhawk and Nemesis ( which are only cosmetically different ) , both of which can use nine weapons , an example is the AS @-@ 3 Tow Missile system . That weapon is the only weapon in the game where the player guides the weapon , the players screen is devoted to guiding the missile and leaving the player open to getting hit . But the upside is that it does massive damage and is the largest explosion in the game . The Omega Dawn expansion adds a dropship , and the Fallen Star expansion adds a jetpack . There are three turrets available to the player ( anti @-@ air missile turret , anti @-@ air flak turret , and the .50 caliber anti @-@ infantry machine gun ) . The game uses the PlayStation 3 Sixaxis and DualShock 3 controllers . The game can be set to make use of these controllers ' motion sensing function to allow the players to control aircraft and ground vehicles by tilting the controller in different directions rather than the more conventional methods of using the D @-@ pad or analog sticks . However , a traditional control scheme is the default option . Warhawk offers online and offline multiplayer play . Offline allows for 1 @-@ 4 players splitscreen ( without bots ) . Online features up to 32 @-@ player battles , with the ability to have up to 4 players use one PlayStation 3 in split screen mode ( on non @-@ ranked servers that permit it ) . Players 2 @-@ 4 can enter or exit the game while a match is in progress .
