Blackmill Games and M2H, developers of the World War 1 FPS Verdun, have revealed a standalone expansion called Tannenberg which focuses the action on the Eastern front of that war. The combat is focused on the border of the Russian Empire and Central Powers, with the maps alternating between plains, forests and mountains.
There will be a number of different modes that will support up to 64 players per match, as well as new weapons and uniforms. Tannenberg is expected to release later this year for PC.
