A Major-style broadcast overlay for Counter-Strike 2 matches. It uses live game data to show health, money, weapons, the killfeed and the bomb timer.

About the project
What I built and how.
CS2 can send match data to an address through Game State Integration. A Flask server I wrote in Python receives and simplifies it, and the HTML and JavaScript overlay pulls from that server 10 times a second to update the screen.
The game doesn't report kills on their own, so I work out the killfeed myself: on every update I compare each player's kills and deaths with the previous state to find who got whom.

When the bomb is planted, a dedicated countdown replaces the round timer.
