Hamsterio is an arcade survival game about a hamster in a real backyard. The scale is thrown off: grass is taller than the house and a beetle is the size of a dog.
The hamster attacks on its own — you move, dodge and collect food. Ants, pillbugs, wasps, snails, spiders, beetles, toads, moles and moths come in waves. Snacks level you up, and each level lets you pick an upgrade: a weapon or a charm. Upgrades change the hamster's look and the way you play.
The yard keeps its own schedule: afternoon, golden hour, dusk, then night with lamps and fireflies. While the day holds, there is time to get ready.
Crumbs are spent between runs on unlocking weapons and charms for good. Anything
you open stays in the upgrade roll forever. There are no permanent stat tracks — all power comes from levels inside a run.
How to play
Move with WASD or the arrow keys; on a phone, drag on the left of the screen or use the gamepad stick.
Dash roll: Space, Shift or the A button. A short roll makes the hamster
invincible, so you can roll straight through danger.
Food: bugs drop corn, blueberries and strawberries — that is experience and levels. Cheese heals, the magnet pulls every snack in, coffee speeds you up and a firecracker clears the screen. Smash cookies for loot.
Upgrades: on each level pick a card with 1–4 or the mouse; the reroll button deals fresh options.
Watch your feet and step off the attack line: the yard throws out puddles, webs and acid that slow you down.
To win, hold on until nightfall and outlast the last resident of the yard. After that the game continues in an endless garden.
Fusion: take a weapon to level 4 and its charm to 3, then trade them on the pause screen for one fused weapon — every recipe and its progress is listed there. The season pass premium track unlocks by watching a video.
