Bane forces have found a way into the tunnels! It looks like they drilled in somewhere near the Queen's chambers. They're infiltrating by force, but fortunately the Atta are fighting them all along the way.
We're going to help the Atta out a little bit by taking out the Bane teleporters they've set up in the tunnels. We need to remove them from the equation. They've got a small goop cannister near each of the teleporters, they use it for some kind of power device. Destroy those cannisters and the teleporters will shut down. Make sure you get all of them.
