A full 3D aim trainer that runs in your browser — 13 training modes, human-shaped dummies with headshot zones, game-specific FOV and sensitivity presets. None of Kovaak’s Steam overhead.
▶ Open FPSTrain — freeMost browser aim trainers are 2D canvas games. They train click speed and reaction, but they miss the part that actually matters in modern FPS: tracking a moving 3D human-shaped target with headshot zones. FPSTrain is one of the very few free tools that ships a real 3D environment in the browser.

The Kovaak Gridshot equivalent — classic aim-training target grid for raw speed & precision.
Random-angle targets for flick reaction training. Closest analogue to Kovaak’s Close Long Strafes.
Smooth and chaotic 3D tracking targets — trains the skill that matters most for Apex and Overwatch.
Only headshots count. The most direct rank-lifter for Valorant and CS2 players.
Scenario-style modes that simulate real duel patterns instead of abstract clicking.
