I Played Battlefield 3: 20 min of hands on awesomeness.

This year I was lucky enough to attend E3. First thing I did was get in line for Battlefield. Then I waited in line for two hours...

I did however gleam a bit of info that I thought I would share

Kits:
Four kits similar to 2142: Assault Medic; Engineer; Recon; Support (Support now carries ammo)

Medic could not run with med kit out. worked almost like a grenade. you though it out then go back to gun.

Defib is no longer an "instant click." There is a charge time for the defib where you have to hold the button down for it to work. You can "pre-charge" the defib while running and then time it right for a quick revive.

Support can now "mount" their guns. One of the unlocks for support is a bi-pod. The bi-pod attaches to surfaces when zoomed in and give support a lot more accuracy. However when bi-bod is deployed, support cannot move, and must retract the bi-pod (zoom out) before they can move again.

Squad size:
4 players, however when asked if that was the final size they said that there was still some internal debate going on about that. For the demo they were showing you were locked into squads of 4, but they said changes could still happen.

Squad Spawning:
Squad member can only spawn on SL's (or team spawn points)
SL's however can spawn on any SM (or team spawn point)

Commanders:
They are not ready to release any information at this time (This was there actual response when directly asked about commanders)

Aside from that the graphics looked great, and the animations were very smooth. I'm sure there are a few things i'm forgetting, and I will add them when I think of it. Until then. I will just say. If you have not pre-ordered yet, do it now. You will not be disappointed.
