Down in the west of Los Santos stands a sky-scraping tower with a large black and white clock – and while the building is nice enough to view as it is, players can actually set foot on the very top of the structure through any form of air transport.
on one of the tower's roofs, players will discover various ladders which are placed about to easily get around the upper outside areas.
Should players climb one of these ladders to get to the topmost level of the tower – they get a grand 360-degree view of the entire city, as well as the perfect vantage point for shooting down enemies (and, hey, if you want to be a jerk – other innocent players too).
Air vehicles can also be easily gunned down at this location, and is an unexpected hiding place that can effectively give players cover.
It's also worthy to note that the clock in the tower is connected to real-time and is properly functioning.
