Normally, when a new game comes out, players scour it for miles on end, hoping to find “Easter eggs” that give them special collectibles or abilities otherwise not available in the game. This was certainly the case with Grand Theft Auto V when it released earlier this week, though Rockstar Games had different “Easter eggs” in mind this time around.

With the Collector’s Edition of the game, you’ll find a complete unrollable map for Los Santos and its neighboring Blaine County. However, the real treat is turning off the lights and turning off a UV light. Once you do this, you’ll expose secrets and notes embedded within the map, including circled locations and messages.

One message in particular reads: “Lago Zan Cudo. Great ocean, highway north, through north chumash, 0.5 miles pas Raton Canyon. When guard rain ends, follow the dirt road down the docks. Bring $500,000 cash. Xxxxx.”

Some other messages indicate that Los Santos could be home to strange alien activity, including a picture of an alien with the words “They’re here!” underneath.

Grand Theft Auto V is available now for Xbox 360 and PlayStation 3.
