I have lost count of how many times ive tried to get the "Devil" achievement.

No matter what i do i cant seem to get bad karma, im always between neutral and evil. Why is this so hard to get? This is the last achievement, once i get this i will have 100% completed the game but its just seems impossible.

I would really appreciate any tips/advice.

Cheers-

The easiest way to get the Devil achievement is to pick the "Devil's Highway" perk after advancing past level 29.

It's actually rather hard to keep bad karma, because it's so easy to get good karma. So picking that perk will ensure that you are very evil at level 30.

This also can apply for the Escalator to Heaven, and Karmic Rebalnce perks... if you need to get the "Messiah" and "True Mortal" achievements.
You can get all three achievements on the same character if you Save right before leveling up to level 30.

But to get the "Devil" achievement it states that you have to have bad karma at lv 30, using the Devil's Highway perk perk will set my karma to very evil. So dose that mean to get the achievement you can have bad karma or anything above bad? im confused lol

My character is currently evil, but ive been very evil and done good things like giving out fresh water and donating to churches etc and it only ever takes me down to neutral, it always skips bad.

Lol, the other karma related achievements were so damn easy, why is this one so much hassle?

When you are level 29, and you level-up, pick the "Devil's Highway"
You will get the achievement.

eh... you wont like it but try hacking a "solen" computer terminal about 100 times
i think its 2 or 5 -karma per time, and you need about 100 to be evil

ok, do i need to have good or very good karma when i use that perk though? Im currently lv 23 with evil karma (6th play through)

It does not matter. You can have any type of karma.
The perk instantly gives you the most evil karma. Which then means you instantly get the achievement for being evil at level 30.
