Mod DB offers a new version 3.0 of the Battlefield 1918 modification for Battlefield 1942 (thanks Ant). Here's the description of this World War I mod: "Battlefield 1918 is a total conversion modification for Battlefield 1942. The mod takes Battlefield 1942 into a whole new scenario, the first world war. Next to historically correct equipments and vehicles, we try to recreate the atmosphere of these WW1 battlefields as close as we can, keeping in mind the game we're working with. To achieve this, we've drastically changed the gameplay from the original game like so that you must now rely on teamwork, artillery, trenches and slow vehicles...."
