So, there's this mod called Portal 2 - Ultra Graphics Mod 2020, which basically lets you add some special effects to Portal 2 to make it look a little better. So one day, I had a random idea, I said to myself, "Hey! This mod works for Portal 2, which is a video game that uses the Source Engine, and Half Life 2 also uses the Source Engine. I wonder, if this mod which was made for Portal 2 also works for Half Life 2?". And it really worked! Here are some screenshots of the game using the mod.
