100 Days At Sea is an open-world survival game where you're sent to the middle of the ocean with one goal: survive 100 days and uncover the mystery of the Bermuda Triangle. The game combines exploration, base building, resource gathering, and combat. Your raft will be your home, your fortress, and your lifeline.

Here's everything you need to know to get started.

Your First 10 Minutes

When you spawn into the game, you'll find yourself on or near your raft base. The ocean is huge, and it can feel overwhelming at first. Don't panic—follow these steps:

  1. Get your bearings. Look around and familiarize yourself with your starting location. Check what's already on your raft.
  2. Start gathering resources. You'll need wood, stone, metal, and other materials to build and survive. Look in the water and on nearby floating debris.
  3. Grab your Harpoon. This tool lets you hook resources from a distance instead of swimming to grab them. It's much faster and safer.
  4. Spot nearby islands. Use your map or just look around. There's almost always an island within sight that you can visit early on.
  5. Build one small structure. Make a basic roof or wall on your raft to protect yourself from weather and enemies. Even a small shelter counts.

By the end of your first session, you should have gathered some resources and placed at least one defensive structure on your raft.

Core Mechanics

Gathering Resources

Resources are everywhere—floating in the water, on islands, in buildings. You can grab them by swimming to them, or use your Harpoon to pull them from a distance. The Harpoon saves time and keeps you safer, especially early on. Common resources include wood, stone, metal, and special items like coral or electronics.

Building Your Raft

Your raft is your base of operations. Build structures like walls, roofs, platforms, and defensive towers. These protect you from enemies and weather. The more you build, the more defensible and comfortable your base becomes. Start small—you don't need a mansion to survive day one.

💡 Tip — Build defensive structures first (walls, towers) before decorative ones. Survival comes before style.

Exploration

The ocean has many islands to explore. Each one may have resources, weapons, enemies, or story clues about the Bermuda Triangle. Some islands are safe; others are dangerous. Start with nearby, quiet islands and work your way to tougher locations as you gear up.

Combat

You'll encounter enemies on islands and sometimes near your raft. Find weapons (swords, guns, tools with damage) to fight back. Early weapons are often found on islands or crafted from resources. Don't engage strong enemies too early—retreat to your raft if you're outmatched.

Survival Essentials

  • Resource management: Don't waste materials. Prioritize what you need most right now.
  • Stay alert for storms: Weather can damage your raft and you. A solid roof and walls help protect against this.
  • Visit islands regularly: They have better loot than open water and clues to the mystery.
  • Upgrade your raft constantly: A bigger, stronger base survives longer and stores more.
  • Keep weapons nearby: Always have a weapon on your raft or in your inventory for defense.

The 100-Day Challenge

The goal is simple: survive for 100 days. Each day that passes brings you closer to winning and "getting rich," as the game promises. Days pass automatically as you play. Focus on steady progress—gather resources, expand your base, explore new areas, and defeat tougher enemies. By day 100, you should have a strong raft, plenty of supplies, and answers about the Bermuda Triangle.

💡 Tip — Keep an eye on what day you're on. If you're still weak by day 50, focus on gathering and building rather than exploring dangerous islands.

Common Beginner Mistakes

  • Ignoring your raft's defense. Don't neglect walls and roofs. Enemies and storms will wreck an undefended raft.
  • Rushing into dangerous islands. Scout first. If enemies are too strong, come back later when you're better equipped.
  • Not using the Harpoon. It's slower than swimming to grab resources, but it's faster and safer overall. Use it.
  • Spending too much time on one area. The ocean is huge. If an island feels picked clean, move on and explore elsewhere.
  • Forgetting to upgrade weapons. Weak weapons take forever to kill enemies. Find or craft better ones as soon as you can.

Your Goal Each Day

Adopt this simple daily routine to stay ahead of the survival curve:

  1. Gather resources from the water or nearby islands.
  2. Improve or repair your raft base.
  3. Explore one new area or island.
  4. Fight enemies to get loot and level up your combat skills.
  5. Return to your raft before nightfall (if that's a threat) and rest.

Repeat this for 100 days, and you'll survive the ocean and uncover the Bermuda Triangle's secrets. Good luck, captain!
