Scattered across the map are numerous cell towers. Interacting with the radio equipment at the top of these towers will reveal a portion of the map, including safe houses, bus stops, and diamond briefcases in the immediate vicinity. Strategy: These are simple exploration-based objectives. Locate a cell tower, climb to the top (often involving some light platforming), and interact with the radio. This is an excellent way to fill out your map, discover new fast travel points, and locate hidden diamond stashes. Prioritize activating cell towers in new areas you explore to gain a better understanding of the terrain and available resources. They are usually lightly guarded, making them relatively safe to approach.
