Top 10 Biggest Acts of Betrayal in Video Games

Video games are an immersive medium that allows players to step into the shoes of their favorite characters and embark on epic adventures. They offer an escape from reality and a chance to experience things that would be impossible in real life. But with great power comes great responsibility, and video games often present players with tough choices that can have serious consequences. One of the most common tropes in gaming is the act of betrayal, where a character turns on their allies or friends for personal gain or other reasons.

Betrayal in video games can take many forms, from a surprise attack during a mission to a character switch that reveals a hidden agenda. It can be heartbreaking, infuriating, or even shocking, leaving players feeling a sense of disbelief or betrayal themselves.

Not long after they arrive, Pigma betrays the team, allowing Andross to capture them. Luckily, Peppy escapes, but James wasn't so lucky.

The Contenders

She acts mysteriously, but Isaac doesn't believe he would be betrayed yet again. Well, he does.
