The re_check: routine performs this check. If no enemy is found, then Torque returns to his normal hunting routines. You probably realise that there is a chance of getting the flag from the dead enemy. However, Shea has not implemented this. I presume that it might be quite difficult to get around the obstruction to the flag, if it is anything other that a single barrier. Also, a long flag-finding sequence would leave Torque vulnerable to attack.
