Update this morning 2.6Gb patch to download
"This update is in preparation for Map Pack 7 and Battlefield: Bad Company 2 Vietnam which is why the update will be approximately 2,6 GB in size. some of the fixes for the Xbox 360 were already rolled out in the previous PC patch. To see a full description, click here.
PC players might encounter some temporary outages or suffer from lag during the server updates (between GMT 08:00 2010-11-30 and GMT 08:01 2010-12-01).
Also make sure you run PBsetup.exe after updating to the latest version of the game.
- Acog and Red dot scope now equippable on MK-14 and G3.
- Fixed an issue where the Bullet Tracers wouldn't display
- Fixed an issue where Play Now wouldn't work
- Added Ticket Count for Conquest end of round.
- Added the server info to the objectives screen.
With the best will in the world it dont take 2Gb to do the above. So the 2gb contains map pack 7.
Confirmed, I look in the install folder and both Map Pack 7 and Vietnam are there.
