10 Final Bosses That Utterly Ruined Their Video Games

6. Frank Fontaine - Bioshock

Getting the right level of difficulty with the final boss is important, but so too is being on the money with your tone and context. Bioshock's Frank Fontaine was neither. In what was something of a genre-busting first person shooter, borrowing elements of survival horrors and RPGs, Bioshock offers players one of gaming's most original and engrossing stories.

Trapped in a once utopian secret city, the player battles countless crazed super-humans and the iconic Big Daddies. Now a part of gaming folklore, these Big Daddies and the battles you had with them were a huge chunk of Bioshock's enjoyability. Tough and at times frankly terrifying, they continually upped the ante as the game wound its way through its wonderfully preposterous plot. A superpowered one, or at least something in keeping with them, would have made a terrific final dual for the game, but instead the developers opted for a plot twist.

Revealing the true identity of the mysterious villain as none other than the Bronx's own Frank Fontaine, he promptly jacks himself up with the game's famous mutagen, chases you around his lab for a bit and goes down with only a few well placed shots. After setting itself up as a dark, broody, and tense shooter, Bioshock's final moments go so far against the grain that all semblance of atmosphere dies with Fontaine. You're shaken out of the brilliant world the developers have created with a flash of light, and the ensuing struggle is so limp that you'd be forgiven for thinking you were playing a different game.
