10 Video Games Where You Can Betray EVERYONE (And Get Rewarded)

Fallout: New Vegas features a variety of factions your character can support in their war for the titular City of Sin. You have the NCR, the Legion, and New Vegas's mysterious founder, Mr. House.

This said, if playing politics with a bunch of powerful organizations sounds like too much of a hassle, the game actually allows you to betray and destroy all of them with the help of one robotic sycophant—Yes Man.

Choosing to side with Yes Man gives you the chance to build your own New Vegas of dreams on the smoldering ruins of every other faction in the game who hoped you could be their ally.

This choice not only rewards you with a unique, neutral Vegas ending but can also provide you with additional perks if you stab your would-be allies in an especially nasty way.

For example, killing Mr. House with a golf club rewards you with extra experience and an achievement, while killing and cannibalizing every faction leader gives you a permanent perk called "Meat of Champions" that gives you extra buffs from eating human flesh.

If you can't beat them, join them. And if you can beat them and don't want to join them, eat them!
