Fallout – How to Get Through Vault 15 and Find the Rope

I finished it. Didn't do more than what I wrote down in question so I'm not sure which is the solution. Probably it was the fix that corrupted my savegame.

Just in case I left all my companions before Base or Master(except Dogmeat,he died while passing force fields). I didn't have more then 10 items. It didn't crash even once. It can be done.

The difficulty of starting out in Fallout is one of my favorite aspects of the game; feels more realistic that way. :) My tactic usually involved making sure my character was a good shot with the pistol starting out. A character build without a decent small guns skill will be much harder. Then until I manage to scrounge better armor and weapons, I try to only pull one enemy at a time. It takes a long time to fight through a level one monster at a time, but it's the most survivable tactic when available. Also make sure you use your resources. Chems or grenades might seem like the kind of thing you should save, but especially at low levels use what you've got!
