Vortex 9 is a free online third-person shooter developed by Mirra Games, originally launched on mobile and brought to browsers as an HTML5 game in March 2025.

Unlike typical military shooters, it leans into absurdity — your character roster includes a cat-person spy, a demon girl, a sentient robot, and a creature with a box for a head.

Each hero is fully customizable and visually distinct on the battlefield, which matters more in a third-person shooter where you see your character constantly.

The core loop centers on fast multiplayer matches across three modes: Team Battle (team elimination), Deathmatch Solo (free-for-all), and Capture Point (territorial control).

Weapons range from conventional rifles and machine guns to bizarre melee options like battle lollipops, each with stats covering damage, accuracy, and fire rate.

You earn gold coins through play to level up your weapons, and a deployable system called Generics lets you create AI helpers that fight alongside you.

Maps are compact and vertical, rewarding jumping, flanking, and surprise attacks from above — a pace that keeps even short sessions intense. Move with WASD and jump with Space.

Vortex 9 uses an inverted mouse layout compared to most shooters: Left-click is aim and Right-click is shoot. This catches many players off guard, so pay attention during your first match. Press C to crouch, G to throw a grenade, and F to pick up items.

Switch between your equipped weapons with 1 through 5. Press M to open the map and Tab for the menu. If you're coming from games like Kour.io or Bullet Force where left-click fires, expect a brief adjustment period.

Before each match, select one of eight characters: John, Jane, Marvin McSpy, Mr Goodboy, Jess Purrfect, Hellen D. Mon, Mercydroid, or Beelzebox. Each hero can be customized visually from head to toe.
