Great boss fights can elevate a game into the echelons of excellence, but terrible boss fights can violently derail their significant momentum.
Then there are those boss fights which take a little from column A and a little from column B, melding sure artistry with deviously frustrating encounter design in a way that leaves players with no idea of how to proceed.
These 10 video game boss fights all had players totally stumped, whether a result of a gimmicky trick the player needed to figure out - looking at you, Hideo Kojima - or perhaps the fact that winning isn't always the route to survival.
These boss fights are all laudably creative and impressively challenging in their own ways, yet many players were undeniably irritated at their own inability to figure out the solution - one which may well have been staring them in the face the entire time.
In retrospect it's much easier to appreciate these encounters, because at the time they left us totally stressed out and swearing enough to make a sailor blush...
