100 Days At Sea Update July 2026 — Alien Invasion Event

By Earnaldo Team • July 4, 2026 • 8 min read

100 Days At Sea kicked off its Alien Invasion event on the evening of July 3, 2026, and the re-theme is impossible to miss — the game's Roblox title now reads [👾] 100 Days At Sea. It's a weekend content event that layers alien-themed rewards on top of the ocean-survival loop, and it landed with a refreshed batch of codes. Here's exactly what changed, what's confirmed so far, and how to get the most out of the event before it wraps.

What's New in the Alien Invasion Event

The headline is the event itself. The game was last pushed at 23:43 UTC on July 3, 2026, and the Roblox title flipped to carry the alien marker right after — the clearest signal that Alien Invasion is now live rather than "coming soon." Trackers had it pencilled in for the July 3 weekend, and the developers hit that window.

This is a seasonal weekend event, not a permanent world expansion. It sits on top of the existing survival structure: you're still stranded in the middle of the ocean, still building a raft base, still hooking resources with your harpoon and pushing toward the 100-day goal and the Bermuda Triangle mystery. The alien theme wraps around that core rather than replacing it.

What's confirmed right now is the re-theme and a fresh code drop tied to the event (full list below). The exact alien enemies, any event-only boss, and the specific event rewards are still being documented as players work through the weekend, so treat the in-game event board as the source of truth for what's dropping. We'd rather tell you what's verified than invent a monster stat sheet that isn't real yet.

How This Affects Gameplay

Events like this one reward players who are already set up to fight. The ocean loop hands you a full roster of 23 classes, and they scale in cost from the entry-level Sailor at 40 Pearls up to the Fire Mage at 750 Pearls. Combat classes like the Swordsman and Sharpshooter matter more than usual when an event leans on enemy waves, so this is a good weekend to have one unlocked.

Your progression carries over untouched. Event content in 100 Days At Sea layers on your existing save — class unlocks, Pearls, Coins, companions, and your raft base all stay put. That means there's no downside to jumping in: you keep everything you've built and simply get access to the seasonal content on top.

The other shift is pacing. Weekend events tend to compress the reward curve, so the Pearls and Coins you pull from codes and quick runs stretch further while the event is live. If you've been sitting on a class you couldn't quite afford, the code Pearls plus a focused session can push you over the line before the alien window closes.

New Codes

The event arrived with a refreshed, working set of codes. As of July 4, 2026, four codes are live, and they hand out a mix of Coins, Pearls, and a free companion. Redeem them early — event codes in this game rotate quickly, and the ones tied to a weekend push are usually the first to expire.

To redeem, open the game, find the Codes button in the menu, type the code exactly as written, and confirm. Codes are case-sensitive, so copy them character for character. The Pearls stack straight into your balance, which is what you'll spend on class unlocks — and the STRANDEDDEVS Companion Chest gives you a helper without touching your Pearl bank.

Because the developers refresh codes around events, keep an eye out for additional alien-themed codes appearing over the weekend. We track the full, regularly-checked list on our 100 Days At Sea codes page, so bookmark it and re-check before the event ends.

Updated Tips and Strategies

Redeem, Then Gear Up

Start every session this weekend by clearing all four codes. That's 45 Pearls and 50 Coins plus a Companion Chest before you've even set foot on an island. Roll those Pearls into a combat class if you don't have one — the Swordsman and Sharpshooter are the obvious picks for chewing through enemy waves an alien event tends to throw at you.

If you're still early, the Sailor at 40 Pearls is affordable almost immediately from the code Pearls alone. It's not a powerhouse, but it gets you into the fight and starts the Coin flow that funds everything after.

Know the Island and Boss Map

The event is themed on top of the game's existing island run, so knowing the boss order still pays off. The core six are the Sand Worm (Desert Island), Ghost Captain (Shipwreck Island), Lava Guardian (Volcano Island), Frost Giant (Ice Island), Kraken (Kraken Zone), and the Bermuda Entity as the final boss on Bermuda Island. Progress through them in roughly that difficulty order and don't over-extend to a boss your class can't yet dent.

Play the Weekend Window

This is a limited event, so front-load your play. Log in early rather than late, grab any new alien-themed codes as they appear, and prioritize the seasonal content while it's active. Once the event ends and the title drops the alien marker, those event-only rewards go with it. For deeper class rankings and survival routing, our full 100 Days At Sea guide breaks down which classes are worth the Pearls and how to survive the back half of the run.

Community Reaction

The event has done its job on the numbers. As of July 4, 2026 the game is holding around 50,000 concurrent players and has pushed past 118 million total visits — a healthy weekend bump for a survival game that launched as a 99 Nights in the Forest-style take on the ocean. The re-theme in the title is the kind of visible signal that pulls lapsed players back in for an event.

Most of the chatter is players comparing notes on what the alien content actually is, since the developers rolled it out faster than the guide sites could document it. That's typical for a weekend event: the codes go public first, and the detailed rewards get mapped out as more people clear the new content. It's a good reminder to trust the in-game event board over any second-hand list this early.

One thing worth flagging honestly: developers routinely tweak event rewards and codes mid-run, and event-only content disappears when the weekend closes. So the exact mix live right now may shift, and anything alien-themed is best treated as limited-time. Grab the codes, bank the Pearls, and enjoy the event while the 👾 is still in the title.
