Surviving the fourth day

[e11]

My big problem is air.

I know I'm supposed to mix those air pills in Lab 13, but it only had half the chemicals needed. And I know I'm supposed to seal the crack in the shuttle with that little metal plate, but I haven't come across a blowtorch or anything like it in the game.

Oh, and I did find some fuel regulator thing, but I couldn't find a place to put it.

There are two sets of chemical vials in the lab, one on the shelf and one on a table. The blow torch is at the construction site. You need to climb the scaffold with the gloves at the restaurant (lightning) or in the motorcycle (bandits) then lower yourself from the buckle with the rope with the hook. You don't need to do anything with the fuel for air but you need an air filter which was in the same place as the calibrator, an air tank, and to fix the air mix for the ship.

I got lucky on my first playthrough and had the other day 3. On my second playthrough I understand how OP had this problem.

If you have bandits on day 3, you won't know that there is a welding kit at the construction site unless you specifically go back and visit it.

I mean, you should expect to go back to places that you can now visit, but sometimes you forget.
