Isolation (Isolation Fever in thumbnail and bearing "Day 4: Frozen Tundra" in the title sequence) opens with Commander w4sted suddenly waking up, convinced something is outside. He is continuing to experience dizziness and blurry vision, but the med bay on the Constitution wreck is too damaged to be of any use. Fortunately he salvages enough to make a rudimentary medbay and even replace his crash-damaged suit with a slightly less-damaged one he found -- fortunately empty. With luck, he hopes to be able to work with his original suit and recover footage of what caused the Constitution's destruction, as his injuries appear to have left him with no memory of what happened.
Unfortunately, it turns out his old suit is completely irreparable and his new suit turns out to be the one that he and Captain Shack had rigged the previous summer for an intern - no suit AI, no servo assist, and the suit warnings are stuck in Russian. Worse, the audio problems with his recording continue to be an issue.
Having to wait for the under-powered medbay to chug through its tests, he continues to beef up his base, building an annex, a parking area for his rover, and adding more solar panels and cameras.
