There is currently an exploit in Black Ops Cold War on all platforms where a person can gain access to a player’s IP, crash their game, or potentially cause other issues. No indication so far of it happening in MWII or Warzone 2.
Activision has not addressed this nor have they stated they’re aware of this problem. Would be best to avoid Cold War till fixed.
i hate that now the worst thing that can happen to your favorite tv show isn’t just “it got cancelled, they’re not making any more” but “all existing episodes of the show have been wiped from the face of the earth”
