After completing the intro missions in Horizon Forbidden West and really getting into the groove of things in the open world, players will quickly realize that the map has lots of different icons to discover. There are campfire locations to unlock, machine zones, Cauldrons, environmental puzzles, rebel camps, and more. After leaving the first major town in the game, players will start to spot semi-tall towers known as Vista Towers, and there are nine to find in Horizon Forbidden West.
