Operation Wolf Returns: First Mission is the remake of the first Rail Shooter which shaped the genre. Originally released for arcade in 1987, this new edition sticks to the DNA of the original game – breathtaking action atmosphere inherited from 80’s action movies – while offering a brand-new design and a leaderboard. A few months ago, a new criminal organization appeared. In addition to their arms and drug trafficking, they have developed a super powerful weapon. After the discovery of several of the organization’s camps led by the mysterious General Viper, two officers have been deployed to learn more about this dangerous weapon and free the hostages detained in the surroundings camps.
