With a single keystroke, PC players have always been able to pull up the console command input and make any changes they wanted to Fallout 4's rendition of the Boston Commonwealth.
Tired of getting blown up in one shot by super mutants with grenades and can't stand how scarce fusion cores are for your power armor? No problem -- just give yourself 10,000 of them.
Console players, on the other hand, have been stuck with vanilla Fallout 4 for far too long -- and while I've sunk a good 50+ hours into the vanilla version, I still think its easily the least satisfying of all the Fallout experiences so far. That's where mods (finally) come in, providing sorely needed changes that Bethesda hasn't gotten around to making and vastly increasing your in-game options.
Unfortunately, there are fewer overall mods for the PS4 due to Sony's restrictions on external assets. But if you want to cheat your way through some of the game's more difficult battles, there's plenty of mods ready and waiting to ease the Sole Survivor's pain (and increase his ammo count).
