Lost Planet: Kill Giant Worm
The first time I killed the giant worm I used the machine gun because you can keep your distance. In this video I've taken the different tactic of grabbing the gatling guns from the VSs first. This gives you alot more firepower at the expense of not being able to run and shoot at the same time. I stayed close to the starting area to minimize the chance of another worm coming along. You never get two but you don't want to waste ammo and time fighting two different worms.
Its hard to tell amongst all the action when the worm is dead, but look closely for the thermal energy dropping from its head and listen for the stange sounds it makes. Like the moth, it then re-emerges, only to go back to ground dead. The tense ingame music then stops for a while, then resumes as another worm attacks.
