It’s Week 7 in Fortnite: Chapter 2 Season 4 and for this challenge, you’ll need to uncover another one of Tony Stark’s secret locations.
To complete this challenge, you’ll need to infiltrate Tony Stark’s hidden Lake House Lab. Once you’ve found the Lake House, the easiest thing to do is to bash your way through the walls at the foot of the staircase a the entrance.
Alternatively, you can punch a hole through the floor to find this basement-level lab. You’ll know you’re in the right place as there will be several computers that read Stark Industries as well as finding his Iron Man suit in a glass cabinet.
This area is likely to get quite busy pretty quickly, so grab a weapon when you can and try to land there first.
Fortnite: Chapter 2 Season 4 – Where to find Tony Stark’s hidden Lake House Lab
Tony Stark’s secret lab can be found between G2 and G3 and is easy enough to spot on the map. Once you reach it, you can either use your pickaxe to smash your way through the brick base of the house or head inside to look for loot and bash your way through the floor.
Watch out for enemies in the house and inside the lab as there are plenty of places to hide. Once inside the lab, loot the blue chests and hang around for a moment until the challenge registers as complete.
There’s also a blue sports car you can pinch to make a quick getaway once you’ve earned all that XP.
And that’s it! You can find our guide for the Wolverine skin challenges here, as well as how to eliminate Stark Robots at Quinjet Patrol landing sites and all the map changes so far.
