Rune

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) 

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.
