I am really curious to see what DICE concocts for Battlefield 4 maps. I saw somewhere that it had been indicated that multiplayer maps would be largely based on the single player maps (as is often the case). Yesterday, there was a leaked text file from the alpha to which many random players currently have access, and it had the names of the potential single player levels. From this, we find one level called "Dam". This makes me wonder if we might have another focused destruction map in which you can blow up a dam, changing the battlefield into more of a naval battle.
I really think they are going to show us some amazing stuff; I just hope they can exceed the hype with lasting replayability.
