Embodiments of the invention relate to systems and methods for multi-player gaming. Some embodiments relate to systems having an improved communications infrastructure and improved handheld game controllers, while other embodiments relate to improvements in handling large numbers of players in the multi-player game when played in a game arena with a single large display screen showing the multi-player game images. In one particular embodiment, a system is provided that has a game server controlling a display system to display the multi-player game on the large screen and a plurality of game controllers. Each game controller has a secondary display means for providing a secondary game display and input means for receiving player input. The system further comprises communication means for enabling communication between the game server and each of the plurality of game controllers. The plurality of game controllers are located in proximity to the large display screen such that it is visible to game players manipulating the game controllers while playing the multi-player game.
