The part of Half-Life which has changed the most.

This shows a pic of a scientist crushed by a crate and 0 days since last injury :)

This shows some neat lighting effects on your way to the test chamber

This pic is pretty weird and I can't really figure it out

This shows an old part of Black Mesa where you get to see a map

Notice the old looking cactus at the bottom of the screen

An old version of the map right after the incident

An old lab from somewhere

Here is an old pic of everyone's favorite scientist that can never get that drink

An old pic of the warehouse like area in H-L

An old pic that has a mirror! But where is the player's reflection?

An old pic right after the incident, notice there is less detail here

Not much of H-L took place outside, and this pic shows an area near the cliffs

Notice in this pic that Barney has the H-L symbol on his back

An old pic of the lab, notice the scientist looks scared even though it looks like this was before the incident

The Alien Grunts in this pic look like they're floating on air, very similar to the ones in the containment chambers in the game now.

Another old pic of a lab area
