The Open Arena: Multiplayer, PvP & .io

A scripted enemy can only surprise you the way its designer imagined. A human opponent surprises you the way humans do — rudely, creatively, and at the worst possible moment. This collection gathers the files where that is the whole point: live FPS lobbies, formal PvP duels and the .io arenas where everyone starts as a snack and the leaderboard is a public promise.

The list mixes tempers on purpose. The shooters are for players who want their opposition armed; the .io files are for players who prefer their rivalry ambient — hundreds of strangers growing, fleeing and occasionally eating each other in one shared tank. Notes mark the loudest rooms and the strangest ones, which are not always different rooms.
