hi everybody can you post all good signs that i hve to know about Glow and some technics please 
No good signs Buddy. The only good sign would be if you crawl out of that hole alive:)
As for techniques - certainly.
1. No need to max your natural Radiation Resistance - just swallow two Rad-X to ensure 95%.
2. On second LVL there is Mr. Handy robot with 100/100 minigun - one of easiest ways to obtain a mini since its loaded with JHP and won't cause much damage to a well armored player
3. On LVLs 2-4 you can kill robots for 100/100 Ass Rifles and Shotguns
4. On LVL 3 there are some lockers which you can lockpick. Mostly junk inside but there is a chance of getting low-tier BPs as well.
5. Lockers on LVL 4 have better chance of spawning good stuff. Especially small lockers at the bottom.
6. AFAIK LVL 5 is not accessible ATM
7. Nothing particularly interesting on LVL 6
Well that's it. Please let me know if there is anything I missed.
