"Mobslinger runs as a background application on S60 device which periodically scans for other users in the vicinity who are also running the mobslinger application. Once detected, a countdown timer is initiated on both phones which alerts the user by sounding an alarm and vibrating the phone. The user then has to ‘draw’ their mobile and enter the randomly generated number which has appeared on the screen as quickly as possible. The person with the fastest time is the winner and the loser is ‘killed’, which means their application is locked out from game-play for a set period of time. The game is playable in a number of different modes which we have termed ‘Quick Draw’ (basic two player mode, ‘Blood Bat’ (shoot everyone in site), Last Man Standing (multi-player competition), and Outlaws (team game)."
