It is a exciting experience When we are playing the game Counter Strike. We always want to capture the screen of some exciting scene. But except for some professional screen capture software such as Hyper snap, ACA Capture Pro, Snag IT,there was still methods for it .
1*you still can press “F5”, it is the Counter Strike game defined capture screen key. The screenshots are put in your "cstrike" folder as a ".bmp" file, such as "de_dust0000.bmp". Your cstrike folder should be located somewhere similar to C:\Program files\counter-strike\cstrike.
NOTE: The actual file path will depend on where you have installed Steam, the example is just for reference.
2* You can take screenshots one at a time using the "PrintScrn" button, but if you use this you need to exit CS and paste the screenshot into a program such as "Paint" and then save the screenshot manually.
I'd strongly recommend the F5 way!
