Half-Life 2 Walkthrough

2. Helpful tips

This game uses advanced physics like no other game before it. What 
I mean is that the environment can, and most likely after you get the 
gravity gun, will be your secondary weapon. Here�s some 
things to remember before going far in this game.

- Watch out for Headcrabs. They are everywhere.
- Barnacle tongues can be useful for getting to high ledges.
- Flammable barrels should NOT be grabbed and pushed by the gravity gun.
- Using grills and barrels as bullet shields saves your life in Nova 
Prospekt, or anywhere for that matter.
- If you can run away, do so.
