Freemans locker
When you begin a game and get your suit look at the lockers One will be marked quotFreemanquot your characters last name Walk straight to it and you will see a photo of his little boy or girl
Gauss CannonJump
A technique used in a lot of EgoShooters is the RocketJump where you point a Rocket Launcher at the ground and fire off a rocket while jumping to be able to jump way higher than usually The downside is that you lose health by doing this and since a rocket in HalfLife takes away lots of health it wouldnt really be of good use
Instead you can exploit another possibility in HalfLife Using the secondary fire mode of the Gauss Cannon instead of the rocket launcher will also launch you high into the air but will not directly deal any damage only eventual falling damage
