I had never played any Tex games and was confused (I am still partially) about not just different endings but different paths .

Steam has some guides HERE , including ways of getting different endings, that I have not checked because they seem to have spoilers, but if you have finished one path it could be useful to get alternative endings without falling all the time in the same.

Hi fellow Boomers,
There is one good you-tube video walkthrough which I found while googling "Tesla Effect walkthroughs". I was stuck at one point in the game so I watched the video WT until the part where I was "stuck", and I found the solution. I'm also using the built-in HINTS system which has helped an awful lot. I'm not worried about losing "points".

Is there anything close to a traditional walkthrough for this game anywhere? I really need one to play this game and I haven't quite gotten skilled on the Video ones.

Ernestine, I found a UHS Hints walkthrough here.
