I wanted to say in the game if you want help outside of tows, after you kill a few guys or monsters or stuff, go to the closest reserection shire and type in /kneel while on, and facing the shire. then a guy will pop up. click him/her and you'll see upgrades for a full 20 mins. It only works in NF, but may work in others that i dont know of.

how ever sadly this does ot work with just the normal game and no exspans
