Game physics

OP-2.2 often makes use of a bunch of game physics tricks and exploits, and the player is expected to go OOB and climb crazy heights sometimes. If you're unfamiliar with STALKER physics, you can watch this video narrated by the same voice actor as Strelok explaining some tricks: (the video is in Russian, turn auto-translated subtitles on)
Another useful trick is crouch jumping, which allows you to jump a little bit higher onto the ledge:
# Walk into the ledge
# Crouch fully (the key can be bound in the settings)
# Jump
# At the highest point of the jump, stop crouching.
A similar trick can be performed using any object (armor, ammo, weapon etc) dropped under your feet as a stepstool.
