I've always heard tales of how hilariously buggy Bethesda games tend to be at launch, but I've never really experienced it first hand -- typically I wait at least a couple of months and grab Fallout or Elder Scrolls games on sale. That wasn't the case with Fallout 4 though, as I fell prey to the hype machine.
I recently got to experience first-hand the frustration of game-breaking bugs while playing through the very first main Minutemen story line quest. The quest is bugged and can't be completed without cheating and bringing up the developer console. It's a good thing I got the game on PC, because I don't know how console players get around that bug without resurrecting a raider and then re-killing him.
While it's not quite Assassin's Creed: Unity, the long-awaited Fallout 4 still has a whole lot of graphical glitches, some of which are a laugh riot and worth the frustration. From disturbing dancing bodies to a dog who likes to swim in mid-air, these are the best Fallout 4 glitches discovered so far!
