The Doom That Came To Roseway is an optional side quest that involves finding notes on a special kind of Toothpaste.
Completing this quest also gives you the Dentastic trophy achievement too
This quest is also connected to the Distress Call side quest too. When you first speak to Anton Crane over at Terra 2 he will mention about a special diet toothpaste and that it has been stolen. Our job is to head to the Underground Lab and get it back.
When you arrive there will be several enemies inside, thankfully the quest markers will guide your way and it is up to you how you want to handle the thief, Cassandra O’Malley.
The above video will also guide you on how to complete this quest and it also shows you the benefits of either killing Cassandra or sparing her.
