How to find and defeat Gunnar in Fortnite Chapter 3?

The latest Fortnite Update V19.20 has added a new mythic boss in the form of Gunnar. You can find Gunnar marching inside the bunker at the newly added POI "Covert Cavern" on the western edge of the map. To take him down, you have to go through his enormous health pool while dodging his attack and that of his IO personal guards.

Tips and Tricks to defeat The Gunnar boss

• Land at the Covert Cavern and collect any weapons of your choice. Apart from guns, collect some healing items and save some building materials. 
• Gunnar has a total of 650 health and 650 shields. So, before you start the combat, assess your resource pool. 
• Once you start attacking him, he will retaliate by firing at you or throwing grenades. Also, he will instruct other IO Guards soldiers to eliminate you. 
• Try to engage the entire fight in mid to long-range and don't go near him as he may charge towards you. Make use of any throwables like Firefly at your disposal.
• You can find a lot of ammo and healing items from the IO Guards. Eliminate them if you need any resources.
• Try to separate the IO guards from Gunnar by repositioning yourself quite often. This allows you to focus your battle on Gunnar rather than his bodyguards.
• Build and take advantage of the high ground when necessary. Also, hide inside any buildings or rooms when you need to heal or reload.
• Dodge, shoot, heal, reload and build. Repeat the process and you will take him down in 5-10 minutes.

Remember, it is far easier to take him down in Duo or Squad mode than in Solos.
