Ever played a FPS but found out that you are horrible at it?
Recently reading a favorite blog of mine, I found a post featuring this game. FPS Trainer is a browser based game that is currently in BETA (with a final release being sometime this month), and it is supposed to be amazing at improving your skills at FPS.
I haven't gone too far into the game just yet, but it seems to be pretty good practice. There is a practice with computer AI, or you can even play with others. I am guessing that the user base is of decent size, but when I played there was not anyone online (off hours in the US though).
I know the BETA is free, but I don't know if it is going to cost money when the final product is released. If interested, I think it would be worth it to sign up at least, in case they give special deals to those who participated in BETA.
