Gunmen Wars

Gunmen Wars is a first-person shooter arcade game that was released by Namco in 1998; it runs on the company's System 23 hardware, and was their first lightgun game to have the lightguns mounted on the front of its cabinets (plural, as up to four players could play simultaneously when a pair of two-player cabinets were linked together!) since Bubble Trouble: Golly! Ghost! 2 (1992). All players must take control of up to four members of the "Red" and "Blue Teams" - and, as in Race On! (also 1998), they shall have their photographs taken by monochromatic cameras on both sides of the cabinets (if there are less than four players, the remaining ones will get filled in for by the CPU, and identified by the word "AUTO" and a Roman numeral between I and IV). The players move by pushing their guns forward to advance, pulling them back to retreat, and pushing them to the left or right to strafe in the respective direction; they can also squeeze the triggers to fire upon their opponents, and revolve by turning the gun in either direction. Diamonds are located everywhere in the game's three areas and can be collected to add to a team's score - and killing another player (regardless of whether he is a human or CPU-controlled) will expose any diamonds he had collected, which the other players can steal for points and restoring their lost energy. Gameplay is also time-based rather than life-based, and once the timer has run out, the players' vital signs and amounts of diamonds collected will get displayed on their respective monitors (and the player with the most shall be declared the winner).
