How do I deal with the purple crystals?
1 of 2: The purple crystals will turn hostile if you get too close. Use a simple weapon like the standard 9mm handgun to get rid of them from a distance.
2 of 2: Or run right up underneath them and whack them with the crowbar. For some reason, they can't hit you if you're directly under them.
