Activision is aware of and working to fix a number of issues being reported with the PS3 version of Call of Duty: Black Ops 2.
Multiple users have reported experiencing connectivity and freezing problems on the official Black Ops 2 forums.
The freezing issue isn't limited to the PS3 edition of the shooter, with some Xbox 360 users also running into trouble, although it seems to be more common on Sony's console.
Activision Support said on Twitter: "We are aware of connectivity issues that some players are facing in Black Ops II on PlayStation 3. We are working on resolution, thank you."
It also retweeted some advice for PC players having problems which was originally posted by a developer at Treyarch, who said: "If you are experiencing crash or performance issues, please make sure your drivers are updated."
In our Black Ops 2 review we called the shooter "another explosive Call of Duty package, even if it doesn't manage to topple previous heights." See what other critics had to say in our Black Ops 2 review round-up.
