10 Most Shocking Gaming Betrayals

10. Big Bo - Binary Domain

Binary Domain is one of the best, most ludicrous games nobody played last generation. Part-Blade Runner, part-Gears of War, it was a robot smashing TPS extravaganza that dealt with trans-humanism and the very real questions posed by artificial intelligence.

Throughout the game, you’re surrounded by an initially very stereotypical cast of characters. There’s the snarky British guy, the butch woman, the strong, quiet, sexy Asian sniper, and of course, the black comic relief sidekick.

The latter is your right hand man, Roy ‘Big Bo’ Boateng, who starts the game as part of the ‘Rust Crew’, a group of soldiers tasked with eliminating robots that can pass as human. In fact, he’s been in the Rust Crew for four years prior to the events depicted in Binary Domain.

But Bo eventually reveals himself to be in the pocket of the US government, who actually wanted to keep the game’s final ‘big bad’ Japanese AI all to themselves. It’s possible for Bo’s betrayal to be revealed as a ruse, depending on whether the player has gained his trust throughout the rest of the game. If not though, he’ll hold you at gunpoint, before jumping in a mech to join the other side of Binary Domain’s final boss fight.

Believe it or not, your best friend going bad is only the second most shocking twist in Binary Doma, but I'll leave that one for you to discover.
