The second, unreleased, phase is titled 'Mare Nostrum: Campagna Italiana 43-45', and will encompass actions in and around Sicily and main land Italy. The first is titled 'Mare Nostrum: Afrikafeldzug 40-43' which concentrates on the actions during the North African Campaign. The Mare Nostrum game project is current subdivided into two phases which reflects the original merger.
The Mare Nostrum team was formed with the merger of 2 separate Red Orchestra: Ostfront 41-45 modification teams Campagna Italiana team and the Burning Sands team. Most play revolves around an Attack and Defend style, whereby one team has to take objective areas from the opposing team in order to claim victory.
Each team then attempts to accomplish objectives varying by game level. Mare Nostrum game play is similar to its parent game, in that players assume the role of an individual infantryman or tank crew during World War II battles in an online multiplayer environment.
