ll right. We promised you some news about our Singleplayer-Part. Here they are:
First of all: we do not release material, which includes nazi or fascism material, and we don´t help to make such material public! We want to demonstrate the confusing circumstances of the Second World War as authentic as possible in a view of a simple german soldier.
The player will be the 19 year old Schütze Johann Siebert and take part of the biggest successful airborne operation of all time: Operation Merkur(mercury): The Invasion of Crete!
As a member of the 3. Kompanie of the 1. Batallion of the Luftlande-Sturmregiment he will be one of the first of 8100 parachutists, who take part of this big operation, landed Western Crete on the May, 20th 1941.The rough first days, in which the operation seemed to be a complete failure and maybe end in a massacre, the player must try to stay alive in three great missions.
Of course, we won´t tell you the objects of each mission yet
