10 Ways Video Games Were Forced To Control Players
2. Kill Too Many Cows, Face The Bovine Defense Force - The Witcher 3: Wild Hunt
It took just days from The Witcher 3's release for players to uncover an exploit which let them quickly accrue crowns - the game's currency - by killing cows in White Orchard village, looting their hides, triggering a respawn by meditating, and rinsing and repeating.
But developers CD Projekt RED were on the ball and quickly realised what was going on, prompting them to release a patch a few weeks later intended to catch those milking the exploit with their pants down.
And that it certainly did. The patch changed the game code to ensure that anyone who killed six cows or more in quick succession would end up facing off against a huge level 27 chort - an immensely strong and frankly terrifying cow-like beast.
Originally, killing a chort would just spawn more chorts continuously as part of the game's "Bovine Defense Force Initiative," but once CD Projekt RED realised that strong players could simply keep killing chorts to farm crowns even faster, they patched it to only spawn a single chort.
