New personalization packs and additional DLC was added to Ghosts earlier today. The packs include the regular weapon camos, player customization options, and the ability to individually purchase DLC weapons separately from the entire DLC pack.
Additionally, the weapons included in the first two DLC packs are available for standalone purchase. The first pack includes the Maverick / Maverick-A2 combo while the second is for the Ripper. Both of these packs are priced at $3.99, while all of the above packs are available for $1.99.
