Ever-informative source on all things Battlefield 3, Alan Kertz, has given out a few new details on the game.
First, when asked if it’s better to get out of a vehicle for faster cap: “No. There’s simply a diminishing return from each additional player, so you can never insta cap like BF2 1.0”
Then, when asked if players can put one country’s optics on the guns of another country (such as the American EOTech sight that was seen on an SKS at PAX): “Yes, but you gotta earn it. That takes time. Lots of time.”
