There’s been quite a bit of excitement over at recently, someone noticed that if you look at some of the glowing Covenant glyphs in Sector 6 resulted in two doors in Sector 8 disappearing allowing access to a previously blocked off area and an empty supply drop.  The Secret Glyph Project got on the wagon and produced a video demonstrating the effect and a whole slew of sub-forums were created to track this phenomenon.

I’m sad to say that  the doors disappear from what appears to be a loading glitch, not from looking at any glyphs. Here’s how I determined this, I encourage you to try this to replicate the results:

Having completed the game I loaded up New Mombasa Streets,  immediately got myself a mongoose and headed to Sector 8 to check on the door.  At this point I should point out that at no time after getting the mongoose did I have the visor on. The door was closed as expected.
I then drove over to Sector 6 and without turning on my visor walked up to the covenant sniper rifle next to the Elites, picked it up and got back on my mongoose (parked near to the Sector exit). I then drove immediately back to the door which was now open with no glyphs sighted.

If you look at a map you’ll see that Sector 8 is actually a twisted mirror of Sector 3 and if you look closely you’ll see that Sector 3 also has a room with funny tiles on it matching the location and design of the one in Sector 8. If you go to this area you’ll immediately feel at home and easily spot the Security door as placed in a mirror fashion to the one in Sector 8. This door opens…

So, it’s my belief that this is just fall out to the way the game engine loads the levels and nothing at all to do with the glyphs, it’s just coincidence that they are located in the area you need to go to de-load the doors.

Certain glyphs lead you to keys areas so for me it’s pretty clear that the glyphs are there for player guidance and to add an air of mystery. Give it it a go, try the experiment above and let me know your results.
