Speak With Andre and Refine Origocrust

To begin Rally and Unite, speak with Andre. Your first objective is to refine Origocrust. This involves collecting raw ore and setting up a Refining Unit and Electric Pylon. Follow the highlighted in-game prompts to complete the refinement process.
Extracting Originium Ore

Collect Originium Ore by using basic attacks on nearby ore deposit nodes.
Speak With Andre and Head to the Originium BPPC

After your discussion with Andre, set out for the Originium Bioprocessing & Purification Center (BPPC).
Traveling via Zipline

To reach the BPPC quickly, use the nearby Zipline Tower.
Repair the Originium BPPC Gate

Once you arrive at the BPPC, interact with the entrance gate to repair it. You will need to use 5 Origocrust refined in the previous step to complete the repairs.
Activate the Teleport Point

Don't forget to activate the Teleport Point sitting to the right of the gate while you're there.
Investigate the Originium BPPC Building

Time for some detective work inside. Activate your scanner to track the footprints, they'll lead you straight to each investigation point.
Eliminate the Landbreaker Squad

A group of panicked Landbreakers will try to jump you during your search. They're weak, so just spam your basic attacks and skills to defeat them easily.
Reach the Objective and Speak With the Trapped UWST Crew

After the fight, head to the objective to find the trapped UWST crew to rescue them
Box Platforming Puzzle

To reach the worker, you'll need to activate the crates and use them as platforms. Swap between the short and tall boxes to build yourself a path up.
Level Up an Operator

Talking to the trapped UWST crew unlocks the leveling system. Just follow the tutorial steps to bump up your Operator's stats.
Deliver the Documents and Parts to Andre

With your team a bit stronger, leave the BPPC and head back to Andre to drop off the document and parts.
Fighting Your Way Out

Expect another squad of Landbreakers to block your exit. Use the same tactics as before to cut through them.
Using Fast Travel

To reach Andre faster, open your map and teleport to the Core AIC Area.
Refine Origocrust Using the Portable Originium Rig

Find an ore deposit nearby and set up the Portable Originium Rig from your inventory. You need to churn out 30 Origocrust units to deliver to Andre.
Set Up a Shredding Unit

Using your Origocrust as a base material, craft a Shredding Unit at the PAC. Follow the tutorial instructions to place the Shredding Unit in your building zone.
Placement and Power
The Shredding Unit won't run without juice, so make sure it's placed near an active Electric Pylon
Produce Originium Powder

Place the Originium Ore into the Shredding Unit to start producing Originium Powder.
Destroy the Rubble at the Hub Base

Teleport to the Hub Base and hand over the Originium Powder to Maymay. Pick up an explosive from the nearby barrel and throw it at the cracked section of the wall. Rescuing the Arsenal Engineer trapped behind the wall will trigger the next event.
Purchase and Enhance Weapons

Saving the Engineer unlocks the weapon shop. Follow the tutorial to upgrade your gear and buy new weapons to improve your team's combat power.
Meet Andre at the Underground Lab

Andre will contact you shortly after. Follow the marker to the Underground Lab and talk to him to discuss your next moves.
