I'm a tad late to the party with this but I wanted to share some thoughts on the white crates that have appeared around Verdansk with 'GUILD' on the sides.
First of all these white crates don't do anything right now. I've tried interacting with them, doing other easter eggs to try and get clues and it seems as though they're just static assets in the game right now.
Secondly, they're obviously teasing Black Ops 7 and The Guild from the game. Based on other easter eggs we've had in Verdansk, it seems as though The Guild is taking over Verdansk for some kind of mission. The Overlook armoury easter egg was considered a breach and that the opening of Stadium and Lab 2 was a second chance to prevent The Guild information falling into enemy hands.
I believe that Black Ops 7 might, in some way, be connected to the Modern Warfare 4 story and this is where I need to put on my tin foil hat…
After completing the Stadium easter egg which opens the executive room, there's plans on the table for a satellite and also Signal Station (the new POI we're getting when Season 1 starts in a few weeks). On a white board is a map of Vondel from Modern Warfare 2 and it's got the Zoo / vet building featured on it.
I'm starting to think that The Guild might be planning something with regards to Vondel and the missile in the middle of Stadium. I could be wrong here, it may not be a map of Vondel and actually a map of Avalon but it does line up perfectly with Vondel's map outline.
The Guild have already launched a warhead before. The easter egg for the original Verdansk nuke has a note next to it which is signed off by a 'Ms L'. A lot of people (including me) thought this was just a play on words for missile but Ms L is featured again in a note inside the Lab 2 stating that the security breach in The Overlook armoury cannot happen again and if it does, they must get to the RV point which is redacted… I'm assuming Signal Station. Perhaps there will be an easter egg that ties into the missile inside Stadium, who knows? But I think the Verdansk storyline might get progressed quite quickly in Season 1 alone.
Finally I saw in another thread that someone mentioned how containers like this were used to blow up Zaya Observatory in Modern Warfare 2 in the Shadow Siege event. These aren't missile containers as they've got doors on either side of them, they don't appear to have a roof capable of opening.
As always, just wait and see what happens in game but all these easter eggs and missing pieces are starting to come together and make a lot more sense.
