Very strange thing in d3_breen_01

[e3_futcha]

Hello. In the last map of Half-Life 2, d3_breen_01, you start in a pod and then Mossman walks you to Breen. In the room you start, above you is an inaccessible area with really strange patterns on the walls. I don't think these can be seen anywhere else but in that inaccessible room. During normal gameplay you can only see a little part of one of the patterns. The patterns are, some kind of ladder, stairs, a pistol, Alyx's gun? And what resembles a crossbow or a cut weapon. Does anyone know what this is about? I'll post pictures.

The answer is in this texture’s normal map, someone should check it.

The texture is metal/metalwall101b, bumpmap for it is metalwall101b_normal and all the "crossbows" and "ladders: are result of wild imagination - it's just some tech-looking spots and lines, which is obvious from screnshot anyway. Waaay overthinking things.
And since Citadel maps were made last, and likely in a haste, I'm not surprised some of wall textures ended up underused throughout the location.

Oh so that's why I couldn't find it, I thought it'd have citadel in its name.

Is that your opinion? It's not like I put any thoughts into this at all. The very moment I saw those walls I saw weapons. I thought it was extremely strange. Don't tell me you don't see at least a pistol on those walls... I can understand why this texture is barely even used at all, if they had put it all over the maps, it would've been extremely distracting to me.

If you don't see anything then oh well, not the first time I see or hear things that others can't but you gotta admit it looks extremely strange, there isn't anything else like it in the game. I try my hardest but I simply can't cannot see symbols...

That piece there really does look like a gun, but it's all a coincidence. If I noticed it on my first playthrough (2005) I'd certainly think there's something to it, but now we just know all the better that it's just sloppy texture work...

Total coincidence. I can see the pistols sorta, but I can't see a Crossbow or any other weaps.
