While Modern Warfare 2 was patched a little while ago in order to eliminate some of the hackers and hooligans plaguing the multiplayer, Infinity Ward still found some areas where they were able to be hit. So, as any developer would do, they patched those areas as well, adding additional security enhancements to the Xbox 360 and PC versions of the game which is slated to release soon. PlayStation 3 users will have to wait a little bit.
Additionally, IW is planning on bringing the 2007 smash-hit Call of Duty 4: Modern Warfare back, by updating the playlists to allow anyone of any rank to play any gametype.
Here is the official post from the IW Forums:
The Modern Warfare 2 patch was successful in eliminating much of the ability of hackers, however we have identified other areas that were vulnerable and have added additional security enhancements to the Xbox 360 and PC versions of the patch. We plan to re-patch the Playstation 3 version as well with these additional updates.
Now that we have these patches on the road to release (out of production) we are looking at how we can further improve the situation on legacy titles such as Call of Duty 4. The first such move will be to update the playlists for Call of Duty 4 to allow access to all game modes regardless of rank.
Which CoD title are you guys currently playing? Black Ops? Call of Duty 2? Or...none?
