9. A Multiplayer/Co-Op Option
Wasteland wandering might not be quite as lonely in Fallout 5, as rumours suggest it could be the first core game in the series to support online multiplayer.
It's easy to see where this speculation originated from. Bethesda has, in the past, admitted that it adds online multiplayer to all of its games during development to see how it would have played out, only to remove it in instances where it didn't work.
Fallout 4 director Todd Howard told Mashable back in 2015...
"Believe it or not, every time we do a game we design a multiplayer mode just to see what we would do."
Presumably Fallout 4 included online multiplayer at one stage in its development, and from the sound of things, Fallout 5 will as well. Whether this is a feature that will be left on the cutting room floor when development has wrapped remains to be seen, but the option to tackle the wasteland in teams would be interesting, if done right.
Online support might potentially make the next entry in the series dangerously close to a MMORPG, but if Bethesda could add co-op or deathmatch-like features without compromising the game's narrative, it could work.
These days, Fallout is as much a first-person shooter as it is an RPG, and after Bethesda's success with the Doom reboot's multiplayer modes, there's a possibility it could take its Fallout experiments a step further next time.
