If we do replace our current weapons with these TFA weapons we will have a larger variety of weapons from ww2 from grenades, to launchers and flamethrowers including the m2 flamethrower and flamenwerfer from Day of infamy along with many others such as the ariasaka rifle and the mosin nagant and the ppsh-41. If we switch to TFA you will lose the ability to customize most of your weapons, so for scoped weapons, there will be a seperate weapon for that-EX: Kar98K Scoped Kar98K, All the rifles are like this but you will be able to purchase both variants of the rifles or whatever gun with multiple variants on the point shop. TFA is a more updated and optimized weapon base bringing more customization to view model and some stuff with the user interface bringing in a more imersive experience when using a fire arm.
