what I posted are pictures of a new multiplayer map in Uc4 (what's gonna be in today's beta, I believe), originally posted by xenorevlis. as we know, the multiplayer maps are based on locations in the campaign, so could this mean there is a flashback sequence in Uc4?
that Uc2 screenshot doesn't show the entire part of the museum explored in that game, furthermore we likely didn't explore all the areas of this fictional museum in Uc2, either.
