Oh! Familiar faces!
I deceived you. The mod I want to present is called "Project Beauty" and does exactly the opposite — it changes familiar faces to unfamiliar ones. Or rather, it enhances and details familiar faces to the point that you won’t recognize them. The mod replaces almost all NPC faces with new, more reasonable and interesting ones. The author took this work very seriously and didn’t just detail the textures but also added characteristic features for each character individually.
For example, Polly Cantelli, who desperately needed some junkie bruises and unhealthy skin:
Author's comment:
I made a couple of changes to Polly Cantelli. When I first played the game, I thought he looked too healthy and decent for a junkie. After all the conversations with him, you really feel that he is truly a user. I made some changes to make him look like one.
Or, for example, Daniel Littlehorn.
Author's comment:
As you might guess, I played a negative character and took the perk "Contract Killer". This perk allows you to work for Mr. Daniel Littlehorn. He pays you for the ears of good people. I didn’t like Daniel’s "design" right away in the game. For dark deeds, I think he looked too friendly. Even in the GECK he is marked as a "good character" (normal, right?). In short, I made several changes that reflect his line of work.
It should be noted that all female characters have become particularly fappable, for example May Wong:

Here's a few more screenshots for comparison. Some do not indicate where the new version is and where the original is, I think you will distinguish them yourself:

The mod weighs only about 4MB.

Phew! I'm tired. This is my first, so to speak, original content on Gamer.ru. Let's see if it's worth it or if it's enough to just copy-paste news? :)
