So much for non-violent play in Postal 2. It cannot be done. Even if you can manage to resist shooting the heads off of the cretins that populate this game, you keep getting attacked by activist groups, radical muslim clerics and rednecks. You have no choice but to fight back.
I do not like the rednecks, as they knocked me out and dressed me up like so:
After escaping and killing about 50 of the yokels, I was able to get back into my normal clothes. But not without walking across town with the gimp outfit on. Everybody laughed at me. Several of them found out it was hard to keep their sense of humor without a head.
Needless to say, I am enjoying the game. I would suggest buying Postal 2 now, since something this twisted will probably be banned soon. As it was, I couldn't find it in any stores and had to order it online.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
