I am new, I tried out the tutorial, one of my tasks was to switch from the pointman to the sniper guy. It said to click on F1. Or F2, either one of them i cant remember. but when I click on those it just does the other command those keys perform. My F1 key does something with my screen resolution, the F2 key turns on and off wifi, the F3 checks battery etc. How can I make the keys work with the game?! Any help back would be much appreciated.
