100 Days At Sea Events Schedule: Alien Invasion and What’s Next

100 Days At Sea, the open-world ocean survival game from Stranded Devs, is in the middle of its biggest event of the summer: the Alien Invasion update, which is live now and closes out on July 10, 2026. This page lays out what is running in the game at the moment and what the developer has lined up next, with exact dates and start times.

The game is one of Roblox’s busier survival experiences right now, with more than 33,000 players in the experience and nearly 140 million visits and over 3.6 million favorites to date. The Alien Invasion event has drawn close to 100,000 players marking themselves interested — comfortably the marquee item on the schedule — while the next update, called The Corruption, is already dated for the following week.

Last updated July 10, 2026. We update this page as Stranded Devs adds and changes events, so the lineup here stays in step with the game.

Current and upcoming events

Alien Invasion (live now)

The Alien Invasion update is the headline event at the moment. Stranded Devs has framed it as a new-content drop, and the developer’s notes point to new islands to explore, new tools, new player classes, and a new raid to take on. It has been the standout draw on the calendar, with close to 100,000 players marking interest — far ahead of anything else scheduled.

The event opened on July 3 and runs through July 10, 2026, closing at 7:00 PM ET (11:00 PM UTC) on the final day. If you want to see the alien content before it wraps, July 10 is the last day it is set to be live.

The Corruption (upcoming)

Next on the schedule is The Corruption, another new-content update, set to begin July 17, 2026. The developer has kept specifics light so far — the teaser only promises that corruption is coming, with more information to follow — so treat the theme as confirmed and the details as still to be announced. It is dated to run for a week, through July 24, 2026.

Interest is building but still well short of the Alien Invasion turnout, with roughly 16,000 players marked interested so far, which is normal for an event whose contents have not been revealed yet.

How the schedule has been running

The two dated events point to a clear weekly rhythm. Alien Invasion runs July 3 to July 10 and The Corruption runs July 17 to July 24, each a seven-day window, and both open at the same time of day: 7:00 PM ET. Both also land on a Friday-to-Friday cycle, so if the pattern holds, Friday evenings are the practical thing to watch for the next drop.
