TUSG.io News

TUSG.io is a free multiplayer survival IO game that runs instantly in your browser — no download, no install, no signup required. Jump in, eat to grow, and fight your way to the top of the leaderboard.

Eat. Grow. Survive.

You start as a tiny cell in a massive shared world. Eat food and smaller players to grow, split to hunt, and dodge the ones bigger than you. But survival is just the beginning.

More than a classic IO game

• Fight NPC factions and bosses — from roaming creeps to rare golden bosses with epic loot
• Loot and craft gear — collect ores, salvage components, and smith wearables that boost your build
• Trade with other players — a live marketplace and black market economy
• Level up — skills, abilities, and quests that persist between runs
• Explore — biomes, treasure, safe zones, and a world that gets more dangerous the further out you go

Play anywhere

TUSG.io works on desktop and mobile — just rotate your phone to landscape and play with touch controls.
