Academy tech lab locations in Fortnite
To complete Fortnite’s “open locked doors in Academy Tech Labs while at Hero Rank A or above” Kickstart mission, you’ll need to either head to Supernova Academy and enter the southeast wing’s basement or visit any lab around the map. Here, you’ll find several locked doors that, upon opening, will progress you through this quest as long as you’re Hero Rank A or higher.

Supernova Academy is the best and easiest place to find them, as this POI is available every round and includes several doors to unlock. However, you can also find up to seven other Academy Tech Labs scattered around, indicated by a flask icon on your map. These are much smaller spots that appear as spherical, spaceship-like structures with an underground lab area.

Opening Supernova Academy’s tech lab doors requires increasing your Hero Rank. Some doors only need Rank C, while others are only accessible after leveling to Rank A. A-rank doors, in particular, are required for your Power Training Kickstart quests.
You’ll know what ranks you need for each door by approaching them and checking their letters. If the letter in front is green, your rank is high enough to open it. Otherwise, you’ll need to venture out into the world and increase it before returning to the academy.

Once you open one of Supernova Academy’s tech lab doors, you’ll have access to small shops, Hero Caches, and holograms containing special gear. You can easily find epic-grade or even legendary items behind these doors, especially if you reach A-rank and open multiple.
How to increase Hero Rank in Fortnite
Hero Rank is a feature in Fortnite Chapter 6 Season 3 that lets you open powerful Hero Caches. Here are some ways to increase your Hero Rank:
- Eliminate other players
- Eliminate demon henchmen
- Return Sprites to their shrines
- Survive Storm Circles
As you survive in your rounds, eliminate other players, and help Sprites return to their shrines, you’ll gradually increase your Hero Rank, letting you open Hero Caches and access Supernova Academy’s tech lab doors. Your rank appears at the side of your screen and resets at the end of each match.
