Heracleum Mantegazzianum

Victorian Era. A threat to all humanity arrives from the English countryside. Some specimens of the dreadful Heracleum Mantegazzianum, also known as giant hogweed, have been spotted. These specimens grow enormously day by day and reproduce just as quickly, rapidly infesting large areas and killing the helpless inhabitants of those regions with their miasma.

An expedition of Mounted Explorers, followed by several battalions of hussars, infantry, and artillery, is arriving at the location. Their task is to eradicate the malignant plant with whatever they have at their disposal: sabers, bayonets, cannons, and bare hands. However, the plants defend themselves with their deadly miasma. There are military structures (fortresses) and civilian structures (hospital, mine, farms, residential districts) in the area.

Active parts of the game include the fortresses (from which hogweed specimens can be spotted and bombarded) and some civilian structures (as will be clarified later). It is essential to keep the railway station operational because further reinforcements from the capital will arrive through it. Then, additional resistance will be needed, as the central command is preparing a fleet of balloons equipped for bombarding the specimens. 

The game is loosely inspired by the song The Return of the Giant Hogweed by Genesis.
