Libertad Crates are guerrilla supply boxes left along Yara's guerrilla paths. They are a steady source of Supremo-Bond, which you need for gadgets and Supremo upgrades.
Follow guerrilla paths through the countryside and check the camps and rest spots along them. Crates are usually off the main roads, so walking or riding a horse the trail makes them easier to spot.
Each crate gives crafting resources, most usefully Supremo-Bond. You spend it at the Workbench on gadgets and Supremo upgrades, so collecting crates early speeds up your backpack builds.
EsperanzaEsperanza is Yara's capital and largest city, and the heart of Castillo's regime. It is under martial law, most open streets are restricted areas, and the story only really sends you there near the end.

Criptograma Chests are locked guerrilla stashes of unique gear hidden near Yara's guerrilla paths. You open each one with two Criptograma Charts found nearby, and all 15 unlock That's Puzzling.
