The Bottom of This

REQUIRES THE MAP AND ADDONS ON YOUR RIGHT. DOES NOT ENTIRELY NEED THE HALF LIFE 2 EPISODES, BUT YOU CAN INSTALL IT IF YOU WANT. ALSO REQUIRES CS:SOURCE FOR THE MAP ITSELF TO WORK.

Your name is Jonathan, a citizen living in an apartment. You were on the roof of your apartment, and now you're running away from zombies sent down from the Combine. You remember barely anything at all, and so you must get to the bottom of this.

Remember, you can use bricks to kill headcrabs. Also, you going to have to backtrack a lot and you'll need to read all the books you find on clues on what's going on and how to progress through the save. I literally made this in one day (5 hours to be exact), so it might be a bit on the difficult or easy side of things.
