The hit tactical shooter is getting another dose of post-launch support from Ubisoft. Dubbed a "throwback to traditional Ghost Recon gameplay," Raven Strike is aimed at the hardcore crowd, with larger maps, complicated missions, and a high degree of difficultly.

The details from Ubisoft are below.

3 new missions in Campaign Mode:

Secure Dawn: a foggy marsh in Kazakhstan where the Ghosts will not be allowed access to advanced technology (no optical camouflage, drone or sensor grenade)

Cold Walker: a train depot on the Russian countryside

Argent Thunder: a nighttime urban setting in Moscow

1 new map in Guerrilla Mode:

Sawmill: face 50 waves of enemies on a foggy Russian countryside

Raven Strike will launch on September 11 for Xbox 360 (1,200 Microsoft Points) and PlayStation 3 ($14.99).
