Teenage Mutant Ninja Turtles

One of the most notoriously difficult NES games, Teenage Mutant Ninja Turtles allows you to take control of all four of the titular turtles, switching between characters at will to take advantage of each of their unique weapons. Consisting of both top-down overworld and side-scrolling platforming segments, TMNT is also home to the infamously frustrating Hudson River level, wherein you have two minutes and twenty seconds to disarm eight bombs.
