15 Most Challenging Open World Video Games

Horizon Zero Dawn

Horizon Zero Dawn features a number of interesting and methodical fights against several different types of machines that require players to constantly switch up tactics on the fly. Aloy has a pretty sizable arsenal of weapons, and players will have to make the best out of it to have any chance of survival. Players will also have to constantly be on the move, so as not to get cornered by a band of deadly machines. Those looking for an even greater challenge should also try The Frozen Wilds expansion, which features even deadlier and brutal types of enemies.
