Joining Forces Walkthrough

No. Step-By-Step Walkthrough
1
Fast Travel to Sand Land, then the Royal Capital, and advance through the objectives.
2
After the cutscene, fast Travel to the Water Supply Point closest to the quest marker in the southern desert.

Head to any of the objectives; at each of them, you'll need to take out a Forest Land Officer's tank. Your own Battle Tank is the best choice for this as the wide open space will allow you to avoid enemy attacks despite its low maneuverability.
3
After taking out all of the Forest Land Officers, fight Rosetta's Tank and get it to 50% health.
4 After the battle, drive back to the Royal Capital and continue through the objectives to end the quest.

Joining Forces Boss Guide

Rosetta's Tank

Sand Land - Rosetta

Rosetta's Tank is a lot bigger and tankier than every other tank in the battlefield, including yours! It can shoot from all directions, thanks to the guns on each side of the tank.

However, just like any other tanks, it is relatively slow. Its size makes it easier to target too!

Take it down by staying close to it to avoid long range attacks, but not so close that you are hit as it spins.

The fight will end when Rosetta's Tank reaches 50% HP, so don't waste healing and boosting items when she's getting near that point.
