Specialisation is key, especially at the start. Focus on your main skill (eg Fighting+weapon of choice, or Spellcasting+Fire Magic, …). You can probably skip levelling Dodging/Armourer for until you are more comfortable with progressing. I usually turn Dodging or Armourer at earliest in the Lair, but it depends a lot.
System Shock remake. Awesome game with no hand-holding, really interesting to play.
