#include < cstrike >

#include < biohazard >



new const PLUGIN_NAME[  ] = "[Bio] Damage Money (Chance)",

        new Chance = random_num( 1, 100 );



        if( Chance > 0 && Chance <= CHANCE ) {

                cs_set_user_money( attacker, cs_get_user_money( attacker ) + floatround( damage ) );

        } else {

                return HAM_HANDLED;
