1.Please add the function for M30 shooting rifle ammunition. Without this feature, the M30 is like a useless old hen that doesn’t lay eggs.
2.Add a shotgun kill mission.
3.We all know that the United States has the automatic shotgun known as the auto-5, while Japan uses the FN style auto-5. Currently, the Soviet Union and Germany are in great need of automatic shotguns, but history has demonstrated that they have designed and used them. Firstly, Germany has designed two types of shotguns: the Becker Revolving shotgun and the Walther Toggle-Locked Semiauto Shotgun. Unfortunately, I can’t find any record of the Soviet Union having designed an automatic shotgun, but history does prove that they ‘used’ such weapons. For example, the Soviet Union could provide the auto-5 from the United States. I believe that automatic shotguns will showcase their advantages indoors in the cramped houses of the Stalingrad map, which will certainly be appreciated by shotgun enthusiasts.
I hope you can adopt these suggestions. If you see this content and take them into consideration, I would be very grateful.
