Alien Invasion Event Guide — 100 Days At Sea

What Is the Alien Invasion Event?

Alien Invasion is a July 2026 content event — not a permanent new island or boss, but a themed escalation of night invasions. Expect alien-flavored enemy waves, potential limited-time Pearls codes via Discord, and boosted community activity around the existing survive-until-dawn loop.

The event follows the June 26 Bonus Pearls + Codes weekend and the June 27 CODES menu launch. Roblox aggregators scheduled Alien Invasion for July 3 alongside ongoing Ice Region content — you can still sail to ice island during the event window.

Stranded Devs has not published a full official patch note breakdown as of July 4, 2026. We update this page when verified gameplay footage or Discord announcements confirm exact enemy types, rewards, or new craftables.

Event Timeline and Code Alerts

July 3, 2026 — Alien Invasion event begins (AllThingsHow, community wikis).

June 27 — Official CODES button live; 20PEARLS launched (+20 Pearls) but expired July 3 after ~13 hours per GamesRadar.

Active legacy codes still work: SEAADVENTURE (50 Coins), STRANDEDDEVS (Companion Chest), 100DAYS (25 Pearls) on codes.

Unverified event strings like ALIENS appear on unverified — test in-game but do not trust aggregator-only lists. Event codes typically expire within hours; redeem immediately when Stranded Devs posts in Discord.

Pre-Event Survival Checklist

Redeem all three active codes on how to redeem — free Pearls and Coins accelerate class unlocks before harder event nights.

Stock 10+ Medkits from crafting and warm meals if Ice Island is in your route — ice region update.

Upgrade raft defenses: Container Shelter, weapon tiers on weapons, and Bonfire placement per raft building.

Assign co-op roles before event night — Sharpshooter DPS, Soldier tank, Medic sustain per co op strategy.

Bookmark codes and enable Stranded Devs Roblox group notifications for flash codes during the invasion window.

Night Defense During Alien Invasion

Core loop unchanged: gather and build by day, defend the raft at night. Alien Invasion likely intensifies wave count or adds themed attackers — treat every night like a mini-boss check until community confirms exact scaling.

Container Shelter reduces exposure during approach sails and may help during docked night cycles — see night survival for full night mechanics.

Night class (+20% night vision) and Lantern starter tools improve target acquisition during low-visibility invasion phases.

Pirate and ranged classes (Sharpshooter, Cowboy, Pirate) outperform pure melee when enemies spawn at raft edges or from multiple angles.

Repair kits and spare ammo prevent cascade failures when one breach opens multiple spawn points.

Recommended Classes and Gear

S-tier DPS: Sharpshooter (+25% ranged, +10% crit) for weak-point windows; Pirate (+15% all damage) for mixed loadouts.

Tank: Soldier (+15% defense) blocks heavy hits during enrage-style invasion bursts.

Support: Medic (+15% health regen) sustains the group through stacked night damage plus cold if Ice route active.

Utility: Night (+20% night vision) for visibility; Crewmate (+10% team XP) if grinding event sessions in co-op.

Full rankings on tier list; build synergies on builds.

What to Do After the Event

Resume standard island progression: Volcano → Ice (Frost Giant) → Kraken → Bermuda per survive day 100.

Archive expired event codes on expired — 20PEARLS is the template for how fast Stranded Devs retires promotions.

Return to game updates for the next Stranded Devs patch; winter Ice content remains the largest biome expansion.
