"Locate cavern entrance" is an objective in The Algorithm in Battleborn
Walkthrough[edit]
Head to the North from the panel you just activated to open the way forward.
This will lead you to a bridge. This is completely overrun with a large number of Robot Minions with MX.Deadeyes and MX.Ronin in the towers at the far end of it.
Just past the first set of lights you will find a pair of Minion Teleporters. Off to each side of the bridge you will see another Minion teleporter to deal with. Coming down the middle of it are yet more robots.
When the party makes it across the mid-point on the bridge then the next part of the mission will trigger. You need to Disable shield gate before you can move forward.
After that, the shield will drop and let you move forward. From the Northeastern cavern, there will be a rush of Robot Minions.
In this will be some MX.Raptors among more M1.Gun Bots. These are a good chance for some quick experience before the next boss fight.
Head over to the West from there. You can just run through to reach the next boss that is in your way.
