I was playing Garry's Mod on the GM_Construct map and some ♥♥♥♥ happened. I noticed that if I use a physical gun, then decals with emo textures are left. Then I noticed an NPC, or someone else. He had a Kleiner skin, and he also had a physical gun. But it was in his crotch. I tried to approach and HP started to be removed from me. As a result, I died. He disappeared.
