Yo B187!!
Premium is 50 Euro (49,99 to be exact) and I already bought it.
Only played 2 new maps and 2 new modes. Won very close domination match at some kind of exotic mansion (can't remember the name of the map). Great vertical map with lots of destruction, you can really change how the map looks during firefights. Lots of action, you are engaging enemies left and right. It reminded me of Mexican standoffs in John Woo movies (minus slow motion and pigeons).
Second one was gun master mode at Zimba Tower. Very enjoyable. Got 2nd place overall because couldn't get kills fast enough with single shot sniper rifle. But it was very exciting, especially fighting for the top spot reminded me of good days of racing in GT for the top spot. Also lots of destruction, nice design.
Plus lots of assignments, some new guns and camouflage for it (F2000 camo looks very nice!) and outfits (didn't check them yet).
Overall since I almost don't play any other games recently and would buy all the DLC for BF3 anyway I think it is a good deal with all the bonus stuff you're given. Can't wait for Armored Kill and End Game (riding shotgun on enduro bike while firing javelins may be very exciting

)
See you on the battlefield mate! Cheers.
