Some of the lucky SOBs to have access to the Battlefield 3 alpha have been posting videos on YouTube and boy do they look good. Apart from the frame rate issues (I'm guessing it could be the users system) it looks very, very good. Let's hope that there's more realistic destruction in the game and not just the usual require-a-rocket-launcher-to-blow-things-up. I want to see little details like glass, lights, tires, bricks, etc fall apart and have realistic destruction.
I'm enjoying some of those death animations, the body movement looks great, the rockets don't seem to have that "punch" I expected them to... The other videos looks good, there's more on the channel for you to check out if you're keen, I suggest you do so!
