20 Worst Game Breaking Bugs & Glitches

Back before it was taken down by the hardmen at the World Wildlife Fund, WWE was known as WWF: the World Wrestling Federation. And anyone who was young in the nineties and early noughties remembers their video games with a sense of joyful abandon.

Back when Dwayne Johnson was The Rock, Donald Trump was a goofy celebrity and Vince McMahon was not yet the subject of a federal investigation into sexual trafficking, there was WWF No Mercy, THQ’s final pro wrestling game for the N64. You can play as The Rock, Edge, Andre the Giant, Chyna, Tori, Kane and Mankind, with a massive roster of wrestlers and wrestling-adjacent figures and an expansive Championship mode that makes it endlessly replayable.

But despite the game’s vast improvements on its predecessors, its astonishing sales record, and the memories you made along the way, there is one major issue. The PAL version of the cartridge was released with a glitch that could wipe your save data completely, apropos of nothing but rumoured to stem from poor quality battery systems. So if you’re thinking about dragging out the old Nintendo and getting stuck back into your custom rassler, you might be forced to think again.
