You know, people could, I don't know, provide more evidence one way or another. It's not like the OP is the only one who owns FC3 on PC or anything. I'm surprised this thread isn't full of screenshots of that pistol, which according tois called Shadow (or The Shadow). I would have done it myself if I had the game but I don't so there's that. Anyone else willing to post high-res screenshots of that thing? Also the recurve bow having GLHB on it.
There's every reason to believe those are GB easter eggs in the game given that GLHB on the syringe doesn't really make sense otherwise, the weapon designer is a fan of the site, and stuff like this. Prove me wrong but damnit I want more screenshots!
I would post mine up but most of the people here would just call it fake and a photoshop. Seriously, it isn't. Is it even worth photoshoping?
