The initials of some Totenreich wall weapons spell “EDWARD”
While searching for clues related to the Wrestler's Belt relic in Totenreich, I started looking for patterns among the 17 wall weapons and noticed that six of them can spell EDWARD using their initials:
E - Echo 12
D - DS20 Mirage
W - Warden 308
A - AK-27
R - RK-9
D - Dravec 45
So: E-D-W-A-R-D
The AK-27 and Dravec 45 are also two of the weapons found inside the secret rooms.
Since this is a Grim Relic, I don't think the solution would require buying every wall weapon on the map.
I've already tried buying these weapons in EDWARD order and nothing happened, so it's probably not that simple. It could also just be a coincidence.
But since the Wrestler's Belt relic still hasn't been solved, I thought this was worth sharing. Maybe these initials are part of a sequence, condition, or some other clue that someone might be able to connect to something else.
