Glamping unlocks when you build one of each Camp Facility in solo play. Facilities are the buildings you add to Libertad's guerrilla camps, and each gives its own perk.
1. Go to a guerrilla camp and talk to the Foreman at the Construction Desk. 2. Build a facility you do not have yet. 3. Repeat until all six exist. The trophy pops with the last one.
Build the Bandidos Barracks early to help Alpha Guerrilla, and La Cantina for Fry Cry. Then fully upgrade one facility for Hogar Dulce Hogar.
