Major Malfunction

Only One Survived. Now He Must Be Saved. There is peace in Europe. However, the single-base war never ended. Their radio communications were closed, the codes were burned and the mission was forgotten as politically inconvenient. The message that peace had been made and the fighting had ended was never sent, so the base continued its mission. Only a major is left from the group that carried out the operation, who still operates from a hidden base behind the border. You have been sent on a secret mission to change the Major's codebook so that the withdrawal message can be sent. The mission is dangerous and the major is suspicious of strangers, so you have to act cunningly. Can You Complete The Mission And Escape Before The Situation Explodes?
