The Caustic Caverns open up after Sanctuary is moved. You need to fight your way through the Sanctuary hole in order to get to the zone. Here there are a few side quests to be done. So let’s get started.

Caustic Caverns Side Quests

Borderlands 2 Big Blue

Borderlands: The Handsome Collection – Safe And Sound

This quest is gotten from Marcus in Sanctuary. He wants you to find his safe and kill 25 bandits along the way. The bandits are the easy part.Head to the Sanctuary Hole and start fighting bandits. As you progress through the area you will see the safe fall and Marcus will ask you to retrieve it. Now it is in Caustic Cavern. You need to get to the end of this area in order to get to the Caustic Caverns. Kill the 25 bandits along the way.Once in the Caustic Caverns follow the way point.

Once you get there a boss named Blue will pop up. His weak spot is the blue crystals. I used my rocket launcher and finished him really quick. Open the chest and get the pictures of Moxi.Now you get a choice to turn it into Marcus or Moxi. Marcus will give you a relic(mine gave increased shop timer limits) or give it to Moxi and you will get a shotgun. I took the shotgun because the relic was pretty bad.

Borderlands: The Handsome Collection – Perfectly Peaceful

You can get this quest in Sanctuary. You need to find four quest items then bring them back to beat the quest. There are three side objectives.First one is to kill Cystalisks. This is easy you can crit them by shooting the crystals in their legs. They can be found by the acid pits.Next is to kill some Threshers. There are more than enough of these around so you don’t have to hunt for them.Lastly is Spiderants. You can see them towards the last quest item. There nests are giant white bee hive looking things. Kill them BEFORE you get the last quest item or it won’t count. After that you can turn it in back at Sanctuary.

Borderlands: The Handsome Collection – Minecraft Mischief

This quest can be found while looking for the quest items for Perfectly Peaceful. You will have to push a mine cart to a crusher. Get behind the cart and go forward for it to move. Once it gets to a gate you will have to open the gate and push it through. The switches can be found next tot he door.If you start to get overwhelmed by enemies then stop for a moment and fight them off. If it is going easy for you then you can push right on through.Once it gets tot he crusher you will have to wait until it breaks and grab the eridium. After that you can turn in the quest right there.

That will end the Caustic Caverns side quest guide. Check back soon for more guides!
