"Survive minion ambush" is an objective in The Algorithm in Battleborn
Walkthrough
Now, you have a true horde of minions coming after you. This includes the M1.Blade Bot, Gun Bot, Rocketeer Bots, M1Strikers, MX.Ronin and even MX.Deadeyes. To help with the whole process, try to find and destroy the numerous Minion Teleporters that are scattered throughout the arena. This reduces the overall number of enemies in your way and makes it a bit easier to focus on those central to the ambush.
Make it through this part and your are onto your first mini-boss fight.
