What is your weapon in Koxo.io?
Koxo.io arms every player with a ball and chain that swings from your character rather than being held. Its reach and power come from the movement you put into it, so attacking is a matter of momentum rather than pointing at a target.
How does attacking work in Koxo.io?
Attacks in Koxo.io follow your mouse movements. Large gestures swing the ball across a wide area while small ones keep the chain close and controllable, so the size of the movement you make directly determines the size of the attack you deliver.
What does controlling the mass mean in Koxo.io?
The ball in Koxo.io carries weight and momentum instead of snapping to your cursor. Learning how that mass moves — and how long a big swing leaves you committed — is the central skill the arena asks you to develop over repeated fights.
Is there any equipment or progression in Koxo.io?
No — every player in the Koxo.io arena carries the same ball and chain. Outcomes come down to timing and control rather than unlocks or upgrades, so there is no better loadout to find and nothing to hide behind in a fight.
Can you move while swinging in Koxo.io?
