Update: It''s getting closer, so here's some more info on the Aftermath expansion pack, directly from the horses mouth. This is DICE level artist "Pontus Ryman" bit on the new map. These Snippets are copied from the original Source blog: HERE
A good read in my opinion, hopefully not all hype, if you have the time follow the link to the original blog!
With Aftermath having a post-earthquake city theme I was eager to take what had been established in the single player campaign and bring that into our dynamic multiplayer environment. Just like in the previous expansion pack Armored Kill, the environments in Aftermath are a feature in themselves. You can get a sense of what I mean in this environment flythrough that I created specifically for our blog readers:
Shaking the players
To push the theme even more, I wanted something unique in the level that really was specific not only in comparison to the other maps in the expansion pack, but to all other multiplayer maps in Battlefield 3.
In the single player experience you get to play as an earthquake goes off. I absolutely loved that and wanted it in Epicenter as well. I really wanted to bring it close to the player and not only be heard in the background. I decided to take the audio and trigger setup for an earthquake shake from one of the single player levels into Epicenter as a test, and it worked better than expected. With help from the audio team, effects artist and designers, we turned this idea into a full level specific feature, where the player gets to experience an ongoing aftershock while in multiplayer.
Introducing Urban Exploring
Another element that I personally feel strongly for is exploration — A city that gets hit by an earthquake creates a different landscape that opens up for a lot of exploration. A broken pipe in the ground becomes something you can crawl through; a rift in the street becomes a protective trench; and a pile of rubble becomes a makeshift staircase that takes you to the next level inside a building.
I also wanted there to be plenty of additional paths for players to find. There are a number of places where players can destroy specific doors to open alternate routes. These routes can be very handy when trying to flank enemies or if they want to avoid confrontation. By breaching these destructible doors, players can transition into an interior environment and find new areas that are clearly differentiated from the outdoors.
