Twenty years ago, a cheeky open world game called Destroy All Humans answered that exact question, delivering a gleeful sandbox of destruction where you get to terrorize the human race. But Destroy All Humans’ biggest strength lies in how that lackadaisical tone is folded into the structure of the world and gameplay. It’s essentially a light open world game, where you roam around a handful of distinct areas, including farmland and the city, and complete missions to progress the main story. The Destroy All Humans games were never afraid to get weird and self-referential, which is a large part of why they work so well. But none of that would have been possible without the first game, and the way it subverted the expectations of the alien invasion genre.
