10 Times Video Games Totally Broke Your Trust

Undertale is a game built on subverting expectations. Not only does it like to troll the player by messing with classic game tropes, it also includes plenty of boss battles with plot twists and changing mechanics.

However, the most mind-breaking fight of them all has to be the infamous final confrontation with Sans at the end of the genocide run. The wise-cracking skeleton, in a very disrespectful manner, decides to completely disregard the game's rules and just do his own thing. He attacks the player outside of his turn, tricks them into throwing the fight, and he can even use his "special attack" to keep the player from attacking indefinitely.

Of course, the other enemies in Undertale have their own silly gimmicks as well, but Sans is just blatantly breaking the rules of most mechanics you're taught throughout the game. It makes this already difficult encounter all the more frustrating, especially since you can never tell if the "weakest" monster in the game won't have another trick up his sleeve for you after you survive his Gaster Blasters.
