Mission 4 | Walkthrough Lost Planet Guide
Last update: 11 May 2016
Go forth and start to eliminate all the spiders and their nests. From time to time you'll see a giant moth flying over the valley and dropping egg-bombs. They're not too dangerous, but keep them in mind. At the end of the valley you'll see a rocket launcher buried under the snow. Take it and use the rope to drop down through the hole in the ground. While hanging, use rockets, grenades and explosive barrels to take out as many spiders as you can. They are all over the place, and so are their nests.
Go to the next room and use the anchor to get up. Take the plasma grenades. You'll be facing some heavy snow pirate resistance in the next hall. Stand in the corridor that leads there and take out as many of them as you can from distance. Once you're in the room, immediately turn left and use plasma grenades to destroy the VS. Grapple up to get on the crates. Two Beetles will crawl into the room and make some mess. Use that distraction to take out the remaining opposition and ten leave using the other exit.
Drop down and kill the pirates that are standing on the ledge to the right (you might have to change camera view using the d-pad for this). Shoot down the exploding squids as well. Jump down to the lower platform and once it starts moving grapple up to the ledge where the pirates were standing. Enter the tunnel at the end of the path and get into the new VS, GTB-22. It's faster and can jump higher than the models you've already seen.
Use the double jump to get to the top of the room and jump through the open roof. Once you're there, you can exchange your mech for a new one (it's buried under the snow). There's also a VS Laser Rifle here and a Data Post. Jump up using the nearby big rock as a footstool.
Boss
This fight can be divided into two parts, with the first one being very easy and the second a bit more troublesome. Get yourself a Rocket Launcher and a Laser Rifle. Your target is the wasp's bright yellow abdomen, you have to show some accuracy in order to strike it. It's good to load up the laser's power by holding the trigger. When you take about a half of the insect's health, it will position itself in the middle of the sky and charge on you with its stinger. This attack is quite devastating, so do all you can to jump above the wasp when it's onto it. You'll find two more VS and a few Rocket Launchers around to help you. The second phase of the duel is much more difficult, because the wasp's attack get faster and deadlier. Do tend to jump a lot, that's the best evasion to most of its attacks.
