If you ask me the gordiant is lost planet 2 signiture boss he is seen on the case he has a whole campain demo just for him litterally you only fight him in the demo and i played the demo so much i killed in first try on the highest difficulty. the trick to killin him is split into 2 teams an Alpha team and a Beta team. Alpha team stays in front of him and waits till Beta takes his legs out then Alpha enters him. Alpha consists of 2 memeber with close range wepons Only, belive me theyll need them inside him. Mean while beta team will hit it from the outside making his life bar drain fast but most importantly Beta team must keep him from using his special lightning attack and even more important from going under water as this will kill alpha team. how u keep it from the lighting u ask simply take its face horns out and u take its best attack from it . how u keep him from going under water 3 ways 1. legs. 2.dish out enough damage.3. keep it attacking u until alpha gets out safley. and make darn sure to watch your battle gauge if emptied it will end the battle early so dont capture data post unless you need to.finally bring gordiant down grab up all the ?boxes and have a couple victory posses wit ya buddies bye now.
