There is a blue print to make health packs from leck materials that you find all over the place. Make a bee line for that before you do pretty much anything. Stumbled across it by accident. They also, you can get just a permanent, second am health vessel. I personally have not worried about that, just because it's so cheap for me to make, you know, temporary ones. But i, after beating the first engine, that was my immediate thought was, oh my gosh, i i don't know how anybody would do this without that. That's aility.
