It started as a simple mod to a classic first-person PC shooter. Taking Valve's original Half-Life, a pair of programmers tinkered with the game's script and worked to turn it into a team-based multiplayer romp. The result was a mod called Counter-Strike, which turned 15 on June 19 of this year. Since then, it turned into a retail release and quickly ballooned into a global phenomenon, becoming one of the most influential and beloved multiplayer experiences ever created. As a website with its roots firmly entrenched in PC gaming, Shacknews' Chatty community has some fond memories of battling Terrorists and Counter-Terrorists across the years. Their recollections range from unforgettable encounters, to funny bugs and glitches, to nights that just went on without end. This is a collection of memories from our community about Valve's Counter-Strike.
