Where to find Gunnar in Fortnite Chapter 3

You can find Gunnar at Covert Cavern, a brand new Fortnite POI inside the mountains just north of Camp Cuddle. The southern entrance is heavily guarded, so try one of the secret side entrances instead.

We’ve marked Gunnar’s location with a red ‘X’ on the Fortnite map below to help you locate him:

How to defeat Gunnar in Fortnite Chapter 3

Like any boss in Fortnite, defeating Gunnar won’t be easy: He’s got loads of health and some special moves up his sleeve, including a powerful punch that propels him forward, so you’ll need to come prepared.

We’ve got some tips to help you defeat Gunnar in Fortnite below:

• Take on Gunnar while in a Trio or Squad, as it will be much easier (and quicker) to eliminate him than doing it by yourself.
• Stock up on weapons and healing items before entering Covert Cavern, as you’ll quickly be swarmed by powerful enemies (as well as other players).
• Find a wall or structure you can hide behind when attacking Gunnar. This is especially important if the battle gets overwhelming and you need cover to heal.
• Use assault rifles or sniper rifles to shoot Gunnar from afar, as getting too close leaves you open to more damage from his physical attacks.
• When a blue aura appears around Gunnar’s fist, hide behind something quickly as he’s about to propel himself forward with a deadly punch.
• Once you’ve defeated Gunnar, quickly grab his Mythic Stinger SMG and Covert Cavern Keycard as there will likely be other players trying to add it to their loadout.

Gunnar’s not the only enemy you need to worry about here. Covert Cavern appears to be the Imagined Order’s new base, so it’s crawling with NPC enemies who will come to Gunnar’s aid if alerted.

Considering this is a brand new location on the map, you’ll also have to compete with loads of other players who want to take out Gunnar for themselves. If you’re struggling, wait a few days until thing calm down.

What does the Covert Cavern Keycard do in Fortnite?

Once you defeat Gunnar, you’ll be able to collect his Covert Cavern Keycard, which is needed to enter the secret Covert Cavern Vault. The location of the Vault will be marked once you pick up the Keycard.

Inside the Vault you’ll find loads of of rare Vault Chests that contain high-tier loot. It’s the perfect chance for you and your Squad to create the perfect loadout, which should help you get another Victory Royale.

Remember that you can only use the Covert Cavern Keycard during the match you found it in, so don’t waste your time trying to store it in a Tent to transfer it between matches – it simply won’t work.
