Is HL2 content is in everyone's game

[Grubzer]

I am making a high and low detail contest map, and want to use some HL2 props that still fit tf2 artstyle. Does TF2 has HL2 assets from the beginning, or do i have them because i have hl2/gmod installed on my computer? So should i pack them, or not?

All source engine games have HL2 content within, TF2 included. Some official maps even use HL2 assets in them.

Why? because all of them are built on HL engine?

Yes. Thats why all older source games have "hl2.exe" as their executable.

Not to mention that TF2 itself uses a lot of sound effects from HL2, such as footsteps, impact sounds and health/ammo pickups

Really, it's not just "some" HL2 content. It's all of it. Everything short of the BSPs is there. Unsurprisingly, almost all of it is unused by TF2.
