Version 1.0.9 of TUSG.io is live, and it is a big one for anyone who has ever died wondering what that skill actually does: our free browser survival IO game now ships with a full game wiki, generated straight from the live game data. On top of that, the Arcadia hub finally has something to hunt, and the virus that chases you across the map can now be fought back. Here is everything that changed.
The TUSG.io Wiki is live
The biggest addition in 1.0.9 is the TUSG.io Wiki — a complete, always-current reference for the whole game. It is rendered from the same data the servers run on, so every cooldown, drop chance and stat you read there matches the build you are playing, automatically, after every update.
Start with the beginner’s guide if you are new — it covers your first life, the opening skill build, and how not to donate your mass to the first player who looks at you. From there, dig into:
- Active skills — every skill has its own page with per-level effects, cooldowns and counters, from Dash to Magma Wall.
- Passive abilities — the character sheet under the hood, and which passives pay off when bought early.
- Wearables and loot — all the equippable drops by category, how power levels roll, and where the chase items come from.
- The Golden Boss guide — spawn mechanics, the enrage phase, and how to actually survive it.
- Marketplace & trading, banks, biomes, ores & mining, crafting components and the arena’s hazards — each with their own reference page.

Arcadia has wildlife now
The center spawn, Arcadia, used to be a quiet hub: safe, calm, and — let’s be honest — a little empty. In 1.0.9, passive slimes roam the fields just outside the safe zone. They are level-1 critters that mind their own business: they will never start a fight with a small cell, so new players can explore without being jumped two seconds after spawning.
They are, however, fair game. Hunting them is the fastest first XP in the game and they drop food and the occasional bit of loot — a proper warm-up before you head for the outer rings where the real dangers live. Just know that slimes remember: hit one and it will absolutely fight back.
Chaser viruses can be shot down
You know the chaser virus — the spiky one that locks on and follows you across half the map at the worst possible moment. As of 1.0.9 it is no longer invincible: hit it five times, with ejected mass or any projectile skill, and it pops.
Popping one rewards you exactly like eating one does, including the chance at rare reagent drops. Running away is still a strategy; turning around and unloading into the thing chasing you is now a better one.
Easier to find, easier to share
A round of site work shipped alongside the game changes: links to TUSG.io now unfurl with a proper preview card on X, Discord and everywhere else, the homepage tells search engines (and humans with JavaScript off) what the game actually is, and the forum has fresh discussion topics waiting for your hot takes. You can follow every update from the news page, this dev blog, or by RSS at /feed.xml.
What’s next
The wiki is a foundation — expect it to grow alongside the game, and expect the outer rings to get more distinct personalities in upcoming updates. Until then: jump into the arena, hunt a slime for us, and go pop a chaser virus. TUSG.io is free, runs in your browser with no download, and version 1.0.9 is waiting.
