Strafox

How to Play

Strafox is a counterstrafe training game. Dodge incoming obstacle walls by strafing through the gaps. The game evaluates your counterstrafe timing on every direction change.

What is counterstrafing?

In games like CS2, you slide when you release a movement key. To stop instantly, you tap the opposite key — this is a counterstrafe. The faster you tap, the quicker you stop, and the sooner you can shoot accurately.

Strafox uses the same physics model as the Source engine to simulate this. Movement is driven by the actual Friction + Accelerate functions from the engine.

Timing

Your counterstrafe is rated based on the gap between releasing one key and pressing the opposite:

Perfect	0 – 60ms	Up to 2x score bonus for faster timing
Slow	61 – 150ms	Score penalty
Overlap	Both keys held	Score penalty

Perfect strafes build combos. Each consecutive Perfect multiplies your score. Any Slow or Overlap breaks the combo. Strafes only count when you're moving fast enough — no gaming the system by wiggling at low speed.

Tips

Watch the velocity indicator on your ship — the horizontal line shows your current speed and direction. A perfect counterstrafe brings it to zero almost instantly. Try to time your direction changes so you pass through gaps at zero velocity.
