believed this was clue.
So we were thinking earlier that BLUE BOX is an referring to something else but we couldn't figure out for what. We came up with this idea based on the alphabet order.
B = 2
L = 12
U = 21
E = 5
B = 2
O = 15
X = 24
Use the numbers to find the letters on the box.
If you apply this code to the box that says "HANDLED WITH LOVE FRAGILE EXPRESS" the letters you get are "ALLLAEX" which doesn't make any sense. But Maybe it is an anagram for "ALL LEAX" as in all the Konami Leaks (Silent Hill, Metal Gear Solid, and Castlevania) are in the BLUE BOX. "Handle With Love" meaning take care of the IPs. Here is the original Konami Leak.
