Every new Fallout title arrived with tons of new weapons to offer hence we can expect something similar for Fallout 4. However, Bethesda should really be cautious when designing the new weapons for Fallout 4 so that the game won’t suffer from imbalances or become unrealistic.
To ensure this does not happen in Fallout 4, Bethesda needs to create weapons with an industrialized design. After all, the Fallout series is set in a post-nuke world of 1950s and back then, everything has an industrialized design.
Also, Bethesda needs to keep in mind that the nuke war has destroyed many firearms so guns should be a very rare treat. Perhaps, the game developer can introduce bows and arrows that are made of bronze and looks like a rifle.
The bottom line is that the weapons should be carefully designed as they play a role in making Fallout 4 more realistic than ever. Regardless, we trust Bethesda to come up with the right formula to ensure that Fallout 4 is awesome to play.
