Time to do some gunning. This isn't a hard section of the mission: just shoot anything that moves or looks like it might move. Watch out for the AA cannons on top, as well as RPG crews. Don't stop firing.
TROPHY: If you manage to take out every target with the minigun during this sequence, the "Minigunned" Trophy will be yours.
When your Intruder drops down below the deck line, open fire on the blue fuel pipes to seriously damage the rig and take out big chunks of the deck. You'll rise up again after that and get a second shot at the AA cannons and anything still alive up there.
You'll approach another rig just after that. Repeat the process and concentrate on the AA guns and the RPG teams. As you circle toward the other side, you'll see a drop ship leaving. Clear the deck, and you'll pursue.
Take out the drop ships as you're flying and you'll hit a cutscene slightly after that. When it's over, you'll be on foot again.
Before you leave the Intruder wreckage, you can actually climb up the hill on your right and shoot down on the Helghast amassing below. Your better vantage point will help you clear them out a lot easier than if you were closer to them. Look for explosive red barrels.
Head down into the camp and take cover as you turn along the path to the left. Clear the path going forward, then cut through the hut on the right for ammo and to get to the tanker just beyond. Move to the right of the hut quickly to get some cover.
The tanker is swarming with Helghast, so find a good place to hide for a few seconds while you drop them. A grenade to the top level will set off a chain reaction that's pretty helpful. Pound your way in through and get inside.
Move up to the top deck, being careful of the Helghast at the top of the stairs. You'll find a whole mess of guys both inside and out up here, so stay on the steps so you can back down as you fight them to avoid getting dropped. Use grenades on the interior troops.
Push up and then drop down to the cargo deck, where you'll fight jetpack troopers. Get to cover and try to aim for their heads when they stop moving. There's also a missile launcher trooper at the far end of the ship to be aware of.
Jetpack troopers can be irritating — the best thing you can do is try to avoid them until they land, then lay into them full-force. Rico will do some serious work on them during the fight, which is handy. Make for stairs at the far side as you go.
After a cutscene, you'll get yourself a jetpack. Use it to jump out to the ice flows, then to the ship on the left, which you can move through. At the far side, head to the end of the metal girders and fly across to the rig.
