When the mission starts, grab a gun from one of three chests in front of you, then get to the marker to end up on the roof. The grenade launcher is in the middle, the minigun on the left and the flamethrower on the right. Once on the helipad, run to the edge of the roof and jump off, opening your parachute when you get low enough.

You’ll have to fight through some waves of Zin here, with the first one being just normal ones. The second wave will include more, as well as some Murderbots, while the third and final wave will be some UFOs. Once everything is gone, watch the cutscene that follows and then you’ll be in the Gatmobile.

You need to drive to the mayor’s office (yes, Pierce is mayor), so ignore the enemies shooting at you and just keep driving. When you get there, clear the area of Zin, then get in Pierce’s “car,” which is actually a tank. Just drive a little bit until you get the objective to destroy some tanks.

One or two shots should destroy the enemy tanks.

After the first batch is destroyed, you’ll need to blow up some more, so go ahead and do that. Once a whole bunch are now scrap metal, you’ll be told to go and confront Zinyak. Head to the tower and feel free to kill some Zin out front if you want, then go to the front door to go inside. Despite the large health bar, shoot Zinyak once to bring him to his knees, then press the button prompts to kill him and end the mission.
