Armored Kill has been out for the PS3 for a bit now, but it will finally be released for the Xbox 360 and PC later today. The patch should arrive late next week for the PS3 and early next week for the Xbox 360 and PC. The best news is that the patch is a server side patch, so players do not have to do anything to get the patch.
The patch will address the Gunship spawn time in Rush mode, which is the major complaint that we have heard about.
