At the core of many of our favourite video games is a tale as old as time itself, of the struggle between Good and Evil. Whether those moral pillars take the form of human characters, aliens, shapes hell even conceptual expressions of colour and sound, the end result is the same. It's one opposing force against the other.
However as we've moved through the rapidly mutating video game industry, there has always been a desire to play as the Evil rather than the Good, and we've seen countless examples where you're given free reign to cause chaos and destruction. This can come about through player choice, by selecting the "Evil" campaign option, or even just because the developers never gave you any other course than to play as Santa's naughty list given corporeal form, but much rarer are the video games that let you play as the forces of Good and let you UNLOCK the ability to turn to the dark side.
So let's take a look as some titles that made you work hard, or open your wallets in order to dive into the devilsh world of playing as the main antagonist.
