A first mobile station (102) can be wirelessly linked to a second mobile station (104). A physical location of the second mobile station with respect to a physical location of the first mobile station can be determined. A first player (112) using the first mobile station can be presented an icon (402) representing a second player using the second mobile station. The icon can be presented from a perspective of an eye level view. At least one targeting icon (410) can be presented to the first player to facilitate targeting of the second player. A physical stimuli can be generated from the first mobile station and/or the second mobile station in response to a simulated weapon activation on the first mobile station. The physical stimuli can be a narrowly focused ultrasound beam (302) modulated to generate an audible sound when a propagation of the ultrasound beam is disrupted by a physical object.
