Penguin Weaponry Testing Site is a quest given by the Penguin scientist Dr. Akaggy beneath the Outpost. She asks the player to defeat an experimental weapon, Shockhopper MK I.
After accepting the quest players will also unlock the ability to return to this mission via their ship computer. Completing it will award a Reward Bag and open the quest Advanced Test Drive. It will also open the Penguin Weapon Shop under the Outpost.
This quest was originally a stand-alone boss quest, and was integrated into the mech progression questline in update 1.3.0.
