        printf("counter = %i", counter); 
        new countstr[64]; 
        if(counter != 0) 
        { 
            format(countstr, sizeof(countstr), "Game starts in: %i", counter); 
            GameTextForAll( countstr, 1000, 4);  
        } 
        else 
        { 
            GameTextForAll("START!", 1000, 4); 
            KillTimer(CountTimer); 
        }
        counter--;
        return 1; 
}
