343 Industries investigating Halo 4 problems

343 Industries is looking into issues that some players are experiencing as they try to connect to Halo 4.

Many users have taken to the Halo Waypoint forum to complain about not being able to connect to the main game servers.

It seems as though the problem has been caused by the release of the latest Spartan Ops mission.

"There are a few hundred players who have been unable to connect to our servers since yesterday," said the Halo Waypoint forum team.

"We're investigating now and hope to have an update soon."

Dates for upcoming Halo 4 downloadable content were leaked earlier this week.
