8 Video Games Whose Best Endings You Never Saw

3. Destroy All Humans - Prey

The ending of Prey is a bit of a sticking point for fans, as the epilogue reveals that everything you had accomplished over the course of the narrative was merely a simulation of an event which eventually led to the end of the Earth.

It turns out that you were never playing as Morgan Yu, but an alien creature put into the consciousness of the scientist, and thrown into the same world-ending scenario the real Yu was involved in, in order to analyse the decisions it made.

The plan is to see if the aliens themselves are capable of learning empathy and other human traits, in the hopes of creating a creature able to push back against the scourge currently destroying the planet. Like everything in the game though, you essentially get to decide whether or not this conditioning works, either joining the cause or killing everyone in sight and dooming the human race.

It's the latter option which is the most satisfying, as while it dooms the planet, there's also the implication that it was the humans' own fault for accidentally creating an even deadlier enemy.
