Better have this topic where we can add some stradegies and basic tips, that can then put/update to Guides-section.

I finally figured out the quick 180-degree turn system, the game has that, but there's no info about that in the manuals. You have to press Run + Down to make character turn quick 180 degrees. Trouble with that is that you have to stand still, before you can do it, you can't walk backwards and then just hit a button, you have to stop first. But I noticed that if you keep the run button pressed all the time, you can run forwards, then stop, press down to turn around and then continue running to opposite direction immediately. Works on both, PC and PS1 versions.
