Just Cause 2 add-on Black Market Boom has been released on PC, PSN and Xbox 360.
This costs Ł1.60 on Steam, 160 Microsoft Points on Xbox 360 and $1.99 on PS3. Note that the European PlayStation Store will be updated later today.
Inside the Black Market Boom are three prototype weapons as over-the-top as the game they belong to. There's the Quad Rocket Launcher and the Cluster Bomb Launcher, as well as the Air Propulsion Gun that blasts jets of air powerful enough to send vehicles skywards.
