Yes, you'd have to use a physics system like bullet physics or similar. HL2 uses both Havok and their BSP collision system. This loads the level into memory 2 times and has 2 side by side frames doing collision checks.
If you attach your own physics system (which is easy) to the world and any collidable objects, you'll have to redo some of the lighting effects, shadows mostly. The visual is alot more complicated than collision system because there is no set way of doing shaders and shadows.
