Iron Man returns with new Stark Tech, limited-time modes, and celebration events in Fortnite’s latest major update
Update 31.20 Overview and Release Details
The highly anticipated Fortnite Chapter 5 Season 4 update 31.20 launched on Tuesday, September 17, 2024, with servers going live at 3 AM PT / 6 AM ET / 11 AM BST following brief maintenance downtime.
This substantial content drop represents the second major refresh during the current Marvel-themed season, delivering significant enhancements across Battle Royale, LEGO Fortnite, and introducing an entirely new limited-time mode.
Epic Games continues to expand the popular superhero narrative with weekly content injections and strategic loot pool adjustments, including increased spawn rates for Doom’s island locations and damage buffs for Shuri’s Black Panther Claws.
Players can now immediately access all new features as server maintenance has concluded, making this the perfect time to jump back into the action and explore the latest additions.
Iron Man’s Return and Stark Technology
Tony Stark makes his dramatic return to the island through update 31.20, bringing an engaging new Story Questline and two powerful mythic item sets: Iron Man’s Combat Kit and Iron Man’s Flight Kit.
The Item Shop now features the sleek Mark 45 armor ensemble priced at 1,500 V-Bucks, complete with Energy Collector Back Bling and devastating Energy Blades pickaxes for maximum customization.
Strategic players will find six strategically placed Stark Armories scattered across the map, offering access to Iron Man’s mythic arsenal or War Machine’s weapon collection. The fan-favorite Stark Industries Energy Rifle has also been reintroduced to the standard loot pool.
Pro Tip: The Flight Kit provides superior mobility for repositioning during firefights, while the Combat Kit offers enhanced offensive capabilities—choose based on your preferred playstyle. Stark Armories typically spawn near major POIs, so prioritize landing at these locations for early-game advantage.
Limited-Time Modes and Gameplay Changes
The new Day of Doom limited-time mode shakes up the standard Battle Royale formula with intense 32-player matches divided into two teams of 16 competitors, each faction receiving unique objectives to secure victory.
This innovative game mode utilizes weapons from the current loot pool but upgrades all available firearms to either mythic or legendary rarity, creating consistently high-powered engagements throughout each match.

Advanced Strategy: In Day of Doom, coordinate with your team to control weapon spawn locations since all gear appears at enhanced rarities. The mode heavily rewards team coordination over individual skill, so communication is crucial. Avoid the common mistake of treating this like solo Battle Royale—stick with your squad to complete objective-based win conditions.
New Skins and Cosmetic Content
Update 31.20 introduces Rubius’ Icon Series skin following its September 15th reveal stream, alongside substantial Story Quest rewards, three new bundles, a fresh Ranked skin, the October Crew Pack, and an exciting preview of the Ghost Ridurr Marvel mashup skin.

Reliable leaks suggest upcoming collaborations with Venom and Mephisto may debut later in the season, expanding the Marvel roster even further.
Spider-Zero and Mary Jane Watson skins will reappear in coming days as they’re integrated into LEGO Fortnite through the Lost Isles expansion as buildable LEGO kits.
Collection Tip: The Icon Series skins typically have limited availability windows, so prioritize acquiring them during their initial release. LEGO-compatible skins offer additional value since they work across both Battle Royale and LEGO Fortnite modes.

Fortnite’s seventh anniversary celebration introduces special birthday quests this week, granting exclusive cosmetic rewards alongside returning Birthday Cake consumables and Present items.
These seasonal consumables will reappear across the Battle Royale island once the birthday content becomes active in-game.
Efficiency Tip: Check the Community Goals website daily for new objectives—early participation often provides advantage as some goals require cumulative community effort. Birthday quests are typically time-limited, so complete them within their availability window to secure all free cosmetics.
LEGO Fortnite: Lost Isles Expansion
The Lost Isles content update revitalizes LEGO Fortnite with the triumphant return of fan-favorite Klombos, now tamable, rideable, and responsive to Klomberry feeding mechanics.
This substantial expansion introduces new weapon varieties, additional biomes to explore, and finally delivers the long-anticipated Airship—a fully buildable aerial vehicle that enables extensive map exploration.
Exploration Strategy: Tamed Klombos provide excellent mobility across difficult terrain and can help gather resources. The Airship requires substantial building materials but offers unparalleled exploration capabilities—prioritize its construction for accessing remote areas. New biomes often contain exclusive resources, so systematic exploration pays dividends.
