Season 4 of Fortnite and its Marvel crossover is in full swing, and some famous portions of the map are slowly being claimed by iconic Marvel heroes and villains. During Week One, players went to the new POI, Doom's Domain, which replaced Pleasant Park in the western part of the map. Now, during Week Three, players will get to check out Stark Industries, which has temporarily replaced Frenzy Farms. This is the site of a Week Three Team Challenge that asks players to defeat Tony Stark three times. For completing this challenge, players can earn 50,000 XP toward boosting their Battle Pass.

Stark Industries is heavily guarded by Iron Man's Stark Robots, so players will want to come as prepared as possible. It may not be a good idea to land at this POI right away. Instead, players will want to land nearby to pick up as much armor, ammunition, and healing and shield boosts as they can. This is likely to be a hard-fought area, both because opponents are likely to also want to try and earn the Week Three Weekly Challenge XP and because Tony Stark as an NPC will be a challenging kill. To add a bonus level of difficulty, this challenge cannot be completed in Team Rumble, so players may want to grab a Squad before heading to Stark Industries. Typically, Tony will be found in a computer lab, which may be difficult for players to find at first. Here's how to get to Stark Industries and take on Tony Stark in Fortnite Season 4.

Where to Find Stark Industries in Fortnite Season 4

Because Stark Industries took over as a named POI on the Fortnite map, players should not have too much trouble locating it. It is in exactly the same spot as Frenzy Farms used to be, in the northeast part of the map, just northeast of The Authority. The area is surrounded by a blue ring, almost like a force-shield.

Once players reach Stark Industries, there are a few places they can go. Normally, Tony Stark can be found on the second floor, usually in a computer lab, so players may want to explore the first and third floors, loot any remaining chests for extra ammo or better weapons, and eliminate enemies there before trying to take him on.

If players can manage to find and eliminate a few Stark Robots that opponents have not defeated, they tend to drop the Stark Industries Energy Rifle, which can help the player in the upcoming fight. Tony Stark dons his Iron Man suit for this fight, and his powers can easily take out a player or squad. However, he only fights from a distance, so players should have a chance if they dodge.

Like Dr. Doom in Week One, Tony drops two new Mythic Weapons, Iron Man's Unibeam and Iron Man's Repulsor Gauntlets. These can help players achieve a victory royale as the match draws to a close. He also drops a keycard, like many of the other Fortnite bosses, which grants the player access to the vault on the lower level of the building.

Players can also find Tony's secret lab on the outskirts of the ringed Stark Industries area, before or after taking on Iron Man himself. This is a hidden location, and players will need to know where to go if they want to find it. To reach it, they will need to find a small cabin near the Heart Lake landmark, northeast of the Stark Industries main building. There, they will need to break through the floor to reach the secret underground lab. Players will find display cases with Tony's suits and some items and loot here, but not much else.
