Apparently a "patch" of some sort was released and now the DLC is actually available again and usable. However, the patch does not contain any other fixes.

If this is true you guys are a sorry bunch of developers. Consider me trading in my copy or selling it. IF IT"S TRUE!

Developers? GPG has next to nothing to say about what gets released in their patches or DLC. SE gives them all of the assignments, in fact, SE tells them what to fix. All those PC patches, they were approved by SE, who then told GPG, "Here are some problems, go fix them." If SE doesn't think something is a problem, then it doesn't get fixed. The same would go for the XBox version, although this time Microsoft has a role in this as well.

DLC is now available did you say? im not so sure if you mean they have made an update which basicly just gives you the maps that you get eclusivly to online play on skirmish play aswell then you would be correct sorry guys but seriously cmon ino there trying to help but we need more then just maps weve already played on some communication from either gpg or square enix would be nice

I'm sorry to have to complain but I'm outraged because i just bought the new dlc for 800ms points and found out only the computer version has he new vehicles/units and I think this is a huge let down to the supcom fans on xbox. Please get the mew stuff for the xbox

Some people on the SE forums say that the patch does include a few fixes, but no fix for the important bugs like the mass exploit or the anti-nuke bug.
