They didn't say anything about patching hacks or something like that. Im pretty sure they just change the pointers and add the new items(And hopefully new items to add with GunAdder ). Im also sure that they will release the Freedom Nades and the USA Mask and all these "new" items now. But it can also be possible that i'm completely wrong and they patched all hacks(That happened to some other games i used hacks for a very long time). But we all know that there is no update with new Bugs/Glitches and methods for hacking because you can't fix all that in only 1 Update. If the update will take a longer time you can be pretty sure that no hack will work after it and it will take some time to release now hacks/glitches and tutorials. Just pray that they don't fix everything!
BTW how many hours are gone since they shutdown the servers because i only know the german time atm?
