|**Rewards:** 5222 XP, 496 dollars, 4th Weapon Slot|
First things first, check Moxxi's toy box to find some loot for you, which contains three unique pieces of equipment, Miss Moxxi's Vibra-Pulse (laser), Miss Moxxi's Slammer (shield) and Explosive Kiss of Death (grenade). If any are better than yours, feel free to replace them or just grab them to sell them.
Return to Jack, then use the fast travel station to go to the new area, Hyperion Hub of Heroism. Note that you'll be fighting a lot of Lost Legion enemies here and it's an atmospheric environment, so a fire-elemental weapon would be great. The most annoying enemy you'll run into are the Scouts, who can cloak themselves when they still have shields.
As you approach the first waypoint, the path will be blocked by Zarpedon, blocking your way to the Eye of Helios. Jack says to get to his office, as hopefully you can lower the defenses from there. When you get there, use the scanner and you see it doesn't work. Jack, against his better judgement, suggests using a Claptrap unit to get inside the office.
Use the button to get inside the nearby room, then press the next button to open the crate and let loose the Claptrap unit. Follow it back to Jack's office, only to see it screws up, letting loose some Lost Legion troops, as well as a snow tornado (which can hurt you). Try the scanner again when prompted, which will eventually make more Lost Legion appear.
After one more failed attempt, the door to the office will open, so head inside. Activate the fast travel inside the office, then just wait until Jack orders you to go to Research and Development to rescue Gladstone and the others. You can either teleport back to the beginning or just exit the office normally.
Research & Development
Fight your way past the initial wave of troops, then the second and go through the door at the end, where you'll encounter even more Lost Legion. Blast them all to pieces, then push the button to open the big door with R&D written above it to reveal an exit to that place. Kill the Torks running around, then you'll be able to rescue Gladstone, allowing you to turn in this mission.
Note: Your reward for finishing this mission is the fourth, and final, weapon slot, meaning you can equip up to four different weapons now.
Completed the mission "Home Sweet Home".
