I would have to say that the Lobstermen are my worst enemies. I responded to an attack on a shipping route on an Expert game and after clearing the upper decks I had lost two of my ten men to lobster attacks. I went to clear the lower decks, which was fairly easy until I encountered six lobster in the engine room. They rushed my squad and killed the two soldiers who had just entered through the doors. This happened at the beginning of the second month of the game all I had researched was Gauss pistols, rifles, sonic pistols and only 3/4's of my squad had aqua-plastic. Everyone except two of my soldiers had been wounded. Die Lobstermen!!
