Following the Fortnite update v22.10 for Chapter 3 Season 4, Holo-Chests were added to the game. Unlike normal, rare, and Chrome chests found on the island, players cannot open these simply by interacting with them. Loopers will need to find a key to gain access to the loot that's inside.What makes it really special is that players can see which items they contain. They appear as holograms above the chest, making it easy for players to know exactly what they are getting. With that being said, Epic Games has issued a challenge this week, tasking players to open a Holo-Chest with a Key at a gas station.Open a Holo-Chest with a Key at a gas station to earn 20,000 XP in Fortnite (Image via Twitter/iFireMonkey)Loopers can easily find keys all over the island, so this shouldn't be too hard. Furthermore, since only one Holo-Chest has to be opened, the task at hand is easy. Those who manage to complete it will be rewarded with 20,000 XP. That said, it's time to open up some Holo-Chests in Fortnite.Fortnite News 🦋@FortniteBRNew in v22.10: Holo-Chests!Use one Key to open a Holo-Chest holding an item you desire: Holo-Chests display a holographic preview of what’s inside so you’ll know whether it has what you need before opening it. #Fortnite76957New in v22.10: Holo-Chests!Use one Key to open a Holo-Chest holding an item you desire: Holo-Chests display a holographic preview of what’s inside so you’ll know whether it has what you need before opening it. #Fortnite https://t.co/ZQMdELGruUHow to open a Holo-Chest with a Key at a gas station in Fortnite - A step-by-step guideHere are the steps required to effortlessly open a Holo-Chest using a key at a gas station in Fortnite Chapter 3 Season 4:Land at a location on the map that features a gas stationLook for a key in and around the area while looting for suppliesOnce the key has been found, find and interact with the Holo-ChestChoose the Holo-Chest that has the desired weapon/item and open it using the keyOnce done, the challenge should be completed, and 20,000 XP will be awardedPlayers need to keep in mind that while Holo-Chests can be found all over the island, they will have to open those found at gas stations to complete this challenge.

Although opponents do land at these locations, thanks to the vast open space, there's a lot of room to rotate safely.That said, gearing up and finding supplies is still a number one priority. Only once players are adequately equipped should they look for keys. If by any chance, they cannot find a key at the current location, players can always try their luck at other POIs/landmarks in and around the area.
