Speaking to PSM3 magazine, lead multiplayer designer Lars Gustavsson confirmed the quakes seen in impressive single-player demos are "technically possible" in Battlefield 3 multiplayer games.

"We're still looking into ambient destruction in multi-player; it's still too early to say really," he told the mag. 

"It's technically possible to have earthquakes in multi-player using Frostbite 2. We feel like kids walking into sweet shops with Frostbite - it has so many features we never knew we needed, and we're still figuring out how best to use them.

"It's just the start for this engine. So far, the only limit to the things we can do with it are our own creative restraints."

The Swedish developer's made no secret it wants to stick to the series fundamentals for Battlefield 3, saying it has "no urge to innovate for the sake of innovation."

Some fans might be concerned by the decision to combine Medic and Assault classes then, but Gustavsson argues it's the right move:

"Our main thinking with the medic class is that we want more people in the game, playing, than sat in the spawn menu," he said. "So, the more chances we give team mates to help with things like revives, the better. 

"We constantly evaluate where people are on the battlefield - and as we saw it in Bad Company 2, Medics were rarely equipped to be on the real frontline. It was the Assault class that people took to the front, so it seemed natural to combine the two."
