Swordbattle.io

Swordbattle.io keeps its combat direct rather than adding the usual .io growth mechanic, matches are decided by swordplay itself, timing a swing against an opponent's own attack, rather than by outgrowing rivals through collecting resources first.

Because attacks have real recovery time after a swing, baiting an opponent into committing to a strike and then punishing the recovery window tends to land more hits than trading blows simultaneously. Staying mobile around an opponent rather than facing them head-on limits how easily they can predict your next swing, which matters more here than in a game with health regeneration to fall back on. Narrow One covers similar team-based .io arena combat with bows instead of swords.
