- Every time you hear the whispering voices giving different advice is a good or evil choice that will effect your ending. If you want the good ending listen to the woman, the evil ending listen to the man.
- I don't think they really change how the game plays out at all so go with whatever you want for the ending.
- Don't horde your insanity. The more you use it, the more you level up its power.
- Tossing a flash (or any other) grenade down a burrower hole will instakill them.

- Don't play the sequel. It's not bad, but the plot craps all over the first game by trying to saddle Torque with excess mental baggage.
