Developer MachineWorks uses an "on-screen virtual analog stick" for players to control protagonist Tommy's actions, with on-screen "buttons" to shoot and use powers. A nice touch is that all the buttons are movable, so gamers can properly position them for maximum alien carnage efficiency. There's also various levels of transparency for the controls, so that you can have it just out of site and not cluttering your HUD. Look for Prey on iPhone it In when the title becomes available.
