 Unlike real-time strategy games which are similar in design, "Stalingrad" only allows the player to command pre-existing units already placed on the map - units lost cannot be replaced, as the game does not have a unit creation or base building system.The player must achieve predetermined objectives using their limited units to successfully accomplish a mission.In total there are 36 missions, including 7 bonus missions that are unlocked if the player fulfils certain objectives in preceding levels.
