PC | Submitted by Frozen_SolidPlay original HL levels with OpFor weapons
All you have to do is start OpFor with the cheats on, start a new game or boot camp, and type "map c0a0" to start from the train, "map c1a0" to skip the train intro, or "map t0a0" for the hazard course. Now, just type "impulse 101" to get all the weapons including those from OpFor!!!!!
*WARNING- This can be slightly glitchy since the original HL wasn't made for the OpFor weapons

PC | Submitted by James FarbusFlying Glitch
To do this glitch you will need to have the teleporter gun. Once you have it find a barnacle (those things on the ceiling that eat you if you run into the rope) and run into the rope. It will start to pull you up. Use the secondary function on the teleporter gun when you are getting pulled up (the function that lets you go to Xen). You will appear in Xen for a split second and then you will appear back on Earth, but you will be getting pulled up through the walls and ceilings. It is really cool because you can see nearly all of the area and Xen in one place. To get out of it, throw a grenade. It will blow you up and you will appear at your last save point.

PC | Submitted by struan rutherfordGo to Hazard Course
Just after you have seen Gordon jump into the portal to xen a walkway will collapse and a portal will appear. Jump into the portal and you will appear in xen. A scientist will appear with a gun. Pick up the gun and press the right click button with it out. The gun will start beeping then you will appear in the Hazard Course. There you will find two aliens and shotgun ammo.
