Desperados: Wanted Dead or Alive is a real-time tactics video game developed by Spellbound Entertainment and published by Infogrames exclusively for Microsoft Windows. In the game, the player controls up to six characters in a wild west setting. The protagonist is a worldly knife-fighter and gunslinger, John Cooper. He takes on a bounty to capture a notorious train-robber named "El Diablo".
As Cooper sets off on his quest, he is aided by five other friends and they work together in a real-time, stealth-based structure very similar to that introduced in Commandos: Behind Enemy Lines, although an all-out gunfight is still highly possible in the game. (from Wiki)
