<p><strong>CSB Round Timer</strong> draws a clean <code>M:SS</code> countdown for the round. It is computed from <code>mp_roundtime</code> and the time the round actually started (with <code>mp_freezetime</code> added on so the count matches the real clock), refreshed twice a second. In the final 30 seconds the timer turns <strong>red</strong> to warn players, and the moment the bomb is planted it <strong>hides itself</strong> so the game's own C4 countdown owns the screen.</p><h2>Features</h2><ul><li>Countdown derived from <code>mp_roundtime</code> + <code>mp_freezetime</code>.</li><li>Red highlight in the last 30 seconds.</li><li>Auto-hides after the bomb is planted; returns next round.</li><li>Single HUD sync channel, no chat spam.</li></ul><h2>Installation</h2><ol><li>Compile <code>csb_round_timer_hud.sma</code>, copy it to <code>addons/amxmodx/plugins/</code> and add it to <code>plugins.ini</code>.</li><li>Change the map.</li></ol>
