Four Trax is a racing arcade game that was released by Namco in 1989 only in Japan. It runs on Namco System 2 hardware, and was the third and final Japann-exclusive 16-bit game from Namco to not feature a "legal notice" at startup saying that the game is for use in Japann only (the first two were Beraboh Man and Bakutotsu Kijuutei, which were both released in the previous year). The game plays very similarly to Namco's own Pole Position and Final Lap, except for the fact that it has quad bikes instead of racing cars - and as with the latter of these two (and Suzuka 8 Hours), up to eight players can play simultaneously when four two-player cabinets are linked together.
The players must take control of four quad bikes (which, as with the cars from Namco's own Dirt Fox, are colour-coded - red for Player 1, white for Player 2, yellow for Player 3 and green for Player 4) which are competing in an off-road race. They are given a preset amount of time in which to complete a full lap of the track, and for each lap of the track that is successfully completed, the players' time is extended. However, if one of the players does not manage to successfully complete his current lap of the track before his time runs out, his game will instantly be over and the race continues without him. The players must complete up to 6 full laps of the track to win the game.
