Police 911, also known as Police 24/7, is a light gun shooter from Konami. It features unique motion sensing technology that is able to detect a players movements in front of the cabinet and adjust the screen and gameplay accordingly.
Another feeatures is the ranking system, whereby the player successfully completes each sub-part of a level, they gain a point towards a new rank. The higher a player's rank, the greater bonuses they can receive; growing time increments to start, followed by additional "lives", with the highest rank rewarding the player with 100 additional lives—however, be careful as the player's rank reverts to the bottom whenever they get shot.
Rather than requiring the player to move individual controls, the motion sensor technology allows players to maneuver their body. The player stands on the yellow foot pad, and must duck and dodge left and right during gameplay. The players movements are captured by three infrared sensors. The movements are fed back to the game, and the players actions are reflected on screen.
In the game, you take the part of a young police officer taking part in a raid on a nightclub in the Little Tokyo region and arresting members of a ruthless gang of Japanese organised criminals. The action then spills out onto the streets and players must be careful not to hit innocent bystanders or fellow police by mistake.When the members of the gang are all under arrest, you are chosen to take part in a daring undercover mission in co-operation with the LA police in Little Tokyo.
