Ideas:
Incindiaries--best against the cities and future towns
Armor Penetrating--best against ships and tanks
HE--same we got now, a general purpose egg
Fritz X, Hs-293, Hs-294, TARZON--guided eggs and rockets
Add an option to load 0 MG bullets--some people don't use MG's on cannon planes--adds weight.
More types of rockets (i don't know of much more--u fill in here).
