Just finished this expedition. This one can be a real pain to get through. Here's some tips to hopefully help.

1. This Expedition, more than the first 2 reduxs, is the definition of Do Milestones Out of Order. Seriously, you can do the later milestones early and it will definitely help with the first ones.

2. You're on a hot planet, but you start with a heat shield. Aside from the normal basic stuff you always need for these, mine some Phosphorus when you get the opportunity; it's probably the best option for recharging the heat shield. One patch/vein should be enough to get through the whole expedition.

3. You will get the Minotaur exocraft in this one. It has a few perks here. A) It protects you from the heat without the need for upgrades or charging. B) It can operate 100% underwater without the need for Oxygen. C) The jump pack gets you around MUCH faster than just you on foot.

4. You have one milestone that wants you to Chart Waypoints, or something close to that wording. You will get Plotting Charts (the items that tell you where certain buildings are). This milestone is NOT talking about these items. What it wants you to do is hit 4 different "Chart & Save" points that you find by buildings. IMO, it was not very clear this is what it was asking for.

5. The Climb a Mountain Milestone. Without cheesing it; the best way to get this one is to Track it in the Log (Objective) tab, then climb a "hill". The tracker will tell you how high up you are & the target hight. If you're not high enough, look across the horizon and find a spot higher than you and head for that location. Repeat until you get high enough. You can do this in the Minotaur, it will actually give you a little hight boost.

6. The Low Altitude Maneuvers: once you FINALLY get the ship airborne, what they want you to do is continually Boost in the lower atmosphere for 15 seconds. I found a decent sized lake near my ship. I skimmed the water and had no issues.

I think that's all of the sticking points. Comment any questions and I'll do my best to help.
