Tips for Insane Mode and Messiah achievements?

[AMS Agent Eric Cartman🇺🇦]

I really need help for this, I beat the game on Normal and I really want to beat again on that difficulty level and that achievement at the same time.

Generic tips: Practise the most difficult areas over and over until you can do them easily. Practise constantly toggling your night-vision on and off so that you don't waste too much of your battery. Remember that no matter how much battery you use, when Laird and Nick steal your camcorder, you get it back at about 75% full. Especially practise the bits where enemies are prone to acting randomly. And while there aren't many of them, practise the few jumps in the game that you can miss and would kill you. (Heretic shrine in Town, the jump to the cabin at the end of the Scalled bit, the bit in the mines just after you turn off the power to the wires.) Practise the hell out of the very final bit with Marta because it's not too hard but you really don't want to panic and choke on the last section of the game where it's possible for you to die.

Shady tips: You can go into the game's files and adjust things like how fast you can run, how long batteries last, how quickly you regenerate health. There's no God Mode though. It's not super-legit but I wouldn't judge you because this game is atrociously un-speedrun-able and even a successful run with these benefits takes more than two and a half hours. Insane Mode really sucks.

I suggest practicing the first Val chase in the mines the most (on Nightmare). That's one of the most unforgiving hazards towards the end.

Is Laird's arrow had precise accuracy?
