It is alaways freat to have an excuse to go back and play a great game like GRAW 2. Two DLC packs were recently released. Firstly for free a Gun Pack was made available which added 8 new weapons to the single-player campaign.
More impotantly is the addition of new maps, co-op missions and achievements! There are 5 new co-op missions based on classic Ghost Recon maps and 8 multiplayer maps, 3 of which are entirely new. So dust off that old copy of GRAW 2 and prepare to battle! Go to this LINK for further details on thenew maps and achievements.
