Twist of fate: A war between dimensions

Interdimensional transportation technology is made available by humanity in the year 2071. The first trip meets its end in both silence and gunfire. When another trip was planned with military involvement, ex-soldier and pilot Jonathan Friedrich would be recruited again. With many commendations to his name but a history of mental trauma, the only thing he could have for joining this trip would be a peculiar feeling that he knows the other side of the door. He wasn’t alone on the other side. This dimension was at war, considering newcomers as threats. A reconnaissance trip may be the beginning of interdimensional warfare.
