In the 9th Story mission you need to go to Tundra Express to meet
.
You’ll need to wake him up by having three Varkids scream by burning them.
- You can use a fire elemental weapon
- You can try to gather them up and hit a firemelon, in their first form they will run up to hit you and you can then hit the firemelon
- You can trigger the tall fire pylons to try and burn them.
Make sure you don't kill them.
Once he is awake, you must speak to Tiny Tina. Follow the map and get to her workshop.
After meeting Tiny Tina, you receive a quest update to retrieve her 'badonkadonks'. The markers on the updated map are where you need to go.
Following the train track (and avoiding the train) will lead you straight to one of the badonkadonk's and can then try to avoid most baddies while making a dash for the other. Otherwise you can fight your way through the compound to retrieve them.
Take them back to the worshop, wait a minute, then proceed to the next location. Staying in the water and going around can help you avoid the bad guys across the bridge.
Fast Travel to: The End of the Line.
Make your way through the path of the damaged loaders. Keep an eye out for repair surveyors and EXP loaders that will come running at you.
Then the battle of Wilhelm.
Keep your distance from him, watch out for the loaders, and prioritize the shield repair bots. Use corrosive if you have it and once you take him down, grab the shield core and head to Sanctuary.
