10 Hardest Video Game Boss Fights You Started By Accident
9. Swan - Fallout 4
The world of Fallout is full of oddities and surprises, even if you don't have the Wild Wasteland perk.
Fallout 4's Commonwealth isn't any different in this regard. In fact, on top of mutated creatures and post-apocalyptic settlements made out of baseball stadiums and swimming pools, it can even surprise you with random ambushes, one of which you can accidentally bring onto yourself if you trespass where you don't belong.
When you walk around the Boston Commons area, you can come across multiple signs warning of the danger inside the local park. You then might try to ignore these warnings, seeing as the park area appears to be empty and the signs themselves are old and faded.
However, as soon as you step into the park and approach the nearby pond, your trespassing will awaken Swan—a Pre-War behemoth with armor made out of swan boats and a giant red skull next to his name that indicates this mistake will probably be your last.
Swan is an incredibly lethal opponent, especially at early levels when you're most likely to visit the park, as he is capable of hurling boulders that can one-shot even an armored opponent.
See? That's why reading is important.
