Fortnite Chapter 2 Season 3 introduced a new map that we can all play on. The old map was flooded, largely covering it in water, buying or destroying old POIs, and introducing new ones to explore. One such new area is the Fortilla, which is found in the southwest corner of the map.
The Fortilla is a massive floating fort, the kind of thing some people would build if they had properly embraced the end of the world. You can either fly directly to the location from the battle bus or swim there if you land nearby. The Fortilla is absolutely massive and is one of the most fun areas in the game right now.
It's split into different parts, each is a maze of hallways and stairs, and there's plenty of loot to find. The Fortilla is also the home of Ocean, the boss of the area, and she will drop the Burst Assault Rifle and Bottomless Pitcher when you kill her. She'll also drop a Vault Keycard, which will open a vault in one of the towers, giving you access to massive amounts of items, weapons, and ammo.
Be careful, though, as the vault door is guarded by two sentries who will kill you very quickly if you hit them. The Fortilla is a great place to drop by, especially if you like to combine having lots of early gear with lots of early fights. There's a good chance you'll drop into Fortilla and find that you'll be well-prepared for a winning match.
