I took this screenshot sometime in 1999 of the CS Beta: https://cdn.discordapp.com/attachments/897901358999548004/10...
I took this famous screenshot that was subsequently used in several advertisements for the game: https://cdn.discordapp.com/attachments/672345936449634304/77...
Here's one of them advertising a "personal server" on Planethardware: https://cdn.discordapp.com/attachments/672345936449634304/77...
I also found my screen used in an alienware ad, an Xbox magazine talking about Counterstrike, and Gamespy ads. It was wild.
