Improve your aim at PC FPS games!
This Russian website is made by a leading Counter Strike gamer, and the link is for the version in the English language. There are 3 training area’s, accuracy, reflex, and quickness. You can also register an account to track your progress. The website design is ok, and there are not many adverts, and no pop ups. You just have to cope with one or two War Thunder ad’s! Oh, and yes, as you may have noticed from the image, the translation is not great.
A great way to improve FPS skill, but you will need to log on. A lot.
