@DarkPhilosopher oooopssss.... did an unren with the game, just for fun (and to look inside the pics if there are new stuff)... and then I became adventurous... did a seriously investigation with notepad++ for the scrips.... voila...
player.power_FLY=x Flight (max 3)
player.power_XRY=x Senses (max 3 1=start)
player.power_CHA=x Psychoism (max 3)
player.power_MAN=x Sympathic Link (max 3)
player.power_APP=x Polymorphism ´(max 3)
player.power_WIT=x Mind Control (max 3)
so it is up to oneself to set the powerlevels between 1 - 3... and I tested it with a new game... works like a charm
I suggest not to set polymorphism.... 2 reasons... first you have to buy a better weapon for progress in the storyline... and second... the transformations with this power should be done inside the gamemechanics for being sure
and some observations between my playing with your cheat and seeing the new version, now.... it looks, that if you are buying all powers at globex, that there are some bonus, which are not inside your cheatscript ... maybe I am wrong but sometimes there were bonuses from books, sometimes not... and so on
a playable strategy would be... player.settings at a level for a comfortable playthrough (maybe xray at 3, mindcontrol at 3 and flight at 3, influences to your liking - be aware that initiative is strongly needed) and then play with the ingame-functions, since they should be working... and if you are setting the grade to 100 then there is always time to satiesfy all other goals
