Ya'll remember Half-Life, right?
Anyways, at the ending, when Gman tells you to step into the portal and stuff, just stand there.
The portal eventually closes and G-man says, "Well it looks like we won't be workint together." Then you teleport to this place with an army of monsters and Gman says, "No regrets, Freeman" and then the game ends

If you noclip trough the first monsters you can see that the other monsters are fake.
