Deep Colony: Underwater Base

Dive deep and build the last colony of humanity on the ocean floor!

Deep Colony is a cozy-but-tense colony builder in the spirit of classic shelter games. Dig room by room into the dark, keep your colonists breathing, fed and happy — and be ready when the deep strikes back.

🏗️ BUILD YOUR BASE
• 20 room types: reactors, O₂ generators, algae farms, pearl farms, labs, a gym, a school, a radio room, an aquarium, an observation deck and more
• Merge rooms into bigger halls, upgrade them up to level 5
• Dig deeper into the Midnight Zone and the Abyss for richer rewards

👩‍🚀 LEAD YOUR COLONISTS
• Every colonist has 6 stats: Strength, Tech, Biology, Endurance, Charm and Luck
• Put the right person in the right room and watch production soar
• Colonists fall in love, have children and raise a new generation
• Equip suits, tools, armor and weapons — from a bone spear to a sonic blaster

🔥 SURVIVE THE DEEP
• Fires, floods and creature attacks spread from room to room if you ignore them
• Pirate raids: raiders break your airlock and storm the base
• Giant bosses: Anglerfish, Kraken, Sea Serpent and Titan Crab — tap to fight together

🗺️ EXPLORE
• Explore with no timer, Fallout-style: stay out longer for richer loot — and recall your crew before it's too late
• Craft weapons and armor from blueprints and rare materials
• Build huge colony projects: a Garden Dome, a Survivor Beacon and more — then keep growing them with endless Mastery levels
• Send crews on expeditions to kelp forests, coral reefs and sunken ships
• Make risky choices on the way: open the sealed chest or leave it?
• Bring back pearls, crystals, rare gear and collectible pets
