Rune

Rune cheat codes: 
Open Your user.ini file in a text editor...
Look for "G=" and "T=", there's only one place for each.
Put these there:
G=God
T=CheatPlease

You can put these to other keys also, in case You use those...
When You go to a new level, just hit T and G, and You're set...
(T enables the cheats, so You better hit that first)

You can also type commands "fly" and "walk" to be able to fly and
then come back to normal.

Some other useful cheat commands are:
invisible
ghost
amphibious

A Smart Viking:
Different creatures in the Rune universe will fight with
each other. Waiting to take care of the remaining enemies makes
Ragnar's job a little easier.
