i think tarantula should have the flail/impaler type missile instead for better handling. it getting blocked by terrain is really wancky especially if you consider the all terrain movement too, since it's very often tarantula would move back or foward, to the point that it's on the side of a cliff. at that point it gets blocked, EVEN IF TARANTULA IS ON THE HIGH GROUND IT STILL HAPPENS(play Old Falsell(crab mission) for 1 minute and you will see what i mean). i think this is also made worse by a direct fire missile instead of direct fire laser, since missile also have the chance to turn into the cliff when homing
